<\/span><\/h2>\n\n\n\nBefore getting into the details of the DSA roadmap 2026, let\u2019s quickly understand what DSA actually means. DSA stands for D<\/strong>ata S<\/strong>tructures and A<\/strong>lgorithms. Data structures focus on how data is stored and accessed. Algorithms look at processing this data.\u00a0<\/p>\n\n\n\n\n\n \n Hello World!<\/title>\n <link rel=\"preconnect\" href=\"https:\/\/fonts.googleapis.com\">\n <link rel=\"preconnect\" href=\"https:\/\/fonts.gstatic.com\" crossorigin>\n <link href=\"https:\/\/fonts.googleapis.com\/css2?family=Lato:wght@400;600;700&display=swap\" rel=\"stylesheet\">\n <style>\n .iitr_banner_container {\n font-family: lato;\n display: flex;\n flex-direction: row;\n justify-content: space-between;\n border-radius: 16px;\n background: linear-gradient(88deg, #19000F 24.45%, #66003F 83.33%);\n position: relative;\n\n @media (max-width: 768px) {\n min-height: 450px;\n overflow: hidden;\n flex-direction: column;\n }\n }\n .iitr_banner_content {\n display: flex;\n flex-direction: column;\n align-items: flex-start;\n justify-content: center;\n padding: 20px;\n max-width: 50%;\n\n @media (max-width: 768px) {\n max-width: 100%;\n }\n }\n .iitr_banner_title {\n font-size: 24px;\n font-weight: bold;\n color: #FFFFFF;\n\n @media (max-width: 768px) {\n font-size: 20px;\n }\n }\n .iitr_banner_title_highlight {\n color: #FF0071;\n }\n .iitr_banner_subtitle {\n font-size: 14px;\n color: #FFFFFF;\n margin: 10px 0;\n }\n .iitr_banner_btn {\n display: flex;\n justify-content: center;\n align-items: center;\n padding: 8px 48px;\n background-color: #F8F9F9;\n border-radius: 8px;\n border: 1px solid #E3E8E8;\n font-size: 1.4rem;\n font-weight: 600;\n color: #0D3231;\n text-decoration: none;\n margin-top: 16px;\n\n @media (max-width: 768px) {\n padding: 8px 32px;\n }\n }\n .iitr_banner_image {\n position: absolute;\n bottom: 0;\n right: 0;\n\n @media (max-width: 768px) {\n right: auto;\n object-fit: cover;\n min-width: 100%\n }\n }\n .iitr_banner_image_logo {\n margin-bottom: 16px;\n \n @media (max-width: 768px) {\n width: 240px;\n }\n }\n\n \/* Responsive visibility utilities *\/\n .show-in-mobile {\n display: none;\n }\n .hide-in-mobile {\n display: block;\n }\n\n \/* Mobile breakpoint (768px and below) *\/\n @media (max-width: 768px) {\n .show-in-mobile {\n display: block;\n }\n .hide-in-mobile {\n display: none;\n }\n }\n <\/style>\n <\/head>\n <body>\n <div class=\"iitr_banner_container\">\n <div class=\"iitr_banner_content\">\n <img decoding=\"async\" src=\"https:\/\/d2beiqkhq929f0.cloudfront.net\/public_assets\/assets\/000\/176\/281\/original\/Frame_1430102419.svg?1769058073\" class=\"iitr_banner_image_logo\" \/>\n <div class=\"iitr_banner_title\">\n AI Engineering Course Advanced Certification by \n <span class=\"iitr_banner_title_highlight\">\n IIT-Roorkee CEC\n <\/span>\n <\/div>\n <div class=\"iitr_banner_subtitle\">\n A hands on AI engineering program covering Machine Learning, Generative AI, and LLMs – designed for working professionals & delivered by IIT Roorkee in collaboration with Scaler.\n <\/div>\n <a class=\"iitr_banner_btn\" href=\"#\" id=\"iitr_banner_btn\">Enrol Now<\/a>\n <\/div>\n <!-- Desktop Image -->\n <img decoding=\"async\" class=\"iitr_banner_image hide-in-mobile\" src=\"https:\/\/d2beiqkhq929f0.cloudfront.net\/public_assets\/assets\/000\/176\/282\/original\/iitr_2.svg?1769058132\" \/>\n <!-- Mobile Image -->\n <img decoding=\"async\" class=\"iitr_banner_image show-in-mobile\" src=\"https:\/\/d2beiqkhq929f0.cloudfront.net\/public_assets\/assets\/000\/176\/283\/original\/iitr_2_%281%29.svg?1769059469\" \/>\n <\/div>\n <script>\n document.addEventListener(\"DOMContentLoaded\", () => {\n const pathParts = location.pathname.split(\"\/\").filter(Boolean);\n const currentSlug = pathParts.length > 0 ? pathParts[pathParts.length - 1] : \"homepage\";\n const url = `https:\/\/www.scaler.com\/iit-roorkee-advanced-ai-engineering-course?utm_source=blog&utm_medium=iit_roorkee&utm_content=${currentSlug}`;\n const btns = document.querySelectorAll(\".iitr_banner_btn\");\n btns.forEach(btn => {\n btn.href = url;\n });\n });\n <\/script>\n <\/body>\n<\/html>\n\n\n\n<p><strong>Why is DSA so important? <\/strong><\/p>\n\n\n\n<p>Because every time you use a search engine, scroll through social media, or even run an app on your phone, at all times, DSA is at work behind the scenes.

It is best to spend a few weeks learning and practicing each one:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Arrays & Strings:<\/strong> Foundation of everything in DSA.<\/li>\n\n\n\n<li><strong>Linked Lists:<\/strong> Understand how nodes connect dynamically.<\/li>\n\n\n\n<li><strong>Stacks & Queues:<\/strong> Crucial for recursion, expression evaluation, and scheduling.<\/li>\n\n\n\n<li><strong>Hash Tables (Maps\/Sets):<\/strong> For fast lookups and unique data storage.<\/li>\n\n\n\n<li><strong>Trees:<\/strong> Learn binary trees, BSTs, heaps, and traversal methods.<\/li>\n\n\n\n<li><strong>Graphs:<\/strong> Basics of nodes, edges, BFS, and DFS algorithms.<\/li>\n<\/ul>\n\n\n\n<p>Practice problems regularly. The best way to learn DSA from scratch is to implement every data structure by hand at least once.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Step 4: Core Algorithms (Weeks 8-10)<\/strong><\/h3>\n\n\n\n<p>Once you understand data structures, it\u2019s time to move to algorithms. This is where you will be handling real problem-solving elements.<\/p>\n\n\n\n<p>Key algorithms to learn:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Searching:<\/strong> Linear and Binary Search<\/li>\n\n\n\n<li><strong>Sorting:<\/strong> Bubble, Merge, Quick, and Heap Sort<\/li>\n\n\n\n<li><strong>Recursion & Backtracking:<\/strong> Tower of Hanoi, N-Queens<\/li>\n\n\n\n<li><strong>Greedy Algorithms:<\/strong> Interval Scheduling, Huffman Encoding<\/li>\n\n\n\n<li><strong>Divide & Conquer:<\/strong> Merge Sort, Quick Sort<\/li>\n\n\n\n<li><strong>Dynamic Programming (DP):<\/strong> Fibonacci, Knapsack, Longest Common Subsequence<\/li>\n<\/ul>\n\n\n\n<p>These topics are commonly asked in interviews, so focus on understanding how and why each algorithm works.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Step 5: Advanced Topics (Weeks 11-12)<\/strong><\/h3>\n\n\n\n<p>Once you have learnt the basics, move on to the advanced section of this DSA roadmap. These topics can relatively gain an advantage in an interview:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Advanced Graph Algorithms:<\/strong> Dijkstra\u2019s, Floyd-Warshall, Kruskal\u2019s, and Prim\u2019s<\/li>\n\n\n\n<li><strong>Advanced DP:<\/strong> Matrix chain multiplication, Longest Increasing Subsequence<\/li>\n\n\n\n<li><strong>Segment Trees & Tries:<\/strong> Useful for advanced problem-solving and optimization<\/li>\n<\/ul>\n\n\n\n<p>You don\u2019t need to master all of these at once. Start with understanding their concepts and solving a few problems to get the hang of them.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Step 6: Practice & Problem-Solving (Ongoing)<\/strong><\/h3>\n\n\n\n<p>Just knowing theory can only get you so far; practice is essential! The best platforms to practice DSA are LeetCode, Codeforces, HackerRank, and <a href=\"https:\/\/www.scaler.com\/topics\/challenges\/\">Scaler Problems<\/a>.<\/p>\n\n\n\n<p>Follow a daily or weekly problem-solving routine:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Easy problems:<\/strong> 30 mins\/day<\/li>\n\n\n\n<li><strong>Medium problems:<\/strong> 45 mins\/day<\/li>\n\n\n\n<li><strong>Hard problems:<\/strong> 1 hour\/day<\/li>\n<\/ul>\n\n\n\n<p>Follow the pattern and focus on topics like arrays, strings, DP, trees, and graphs. Gradually move from easy to hard problems. This helps you develop a mindset to tackle unseen problems during interviews.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Bridge your roadmap reading and hands-on solving\u2014join a free live expert session.<\/h3>\n\n\n\n<!DOCTYPE html>\n<html lang=\"en\">\n<head>\n <meta charset=\"UTF-8\" \/>\n <meta name=\"viewport\" content=\"width=device-width, initial-scale=1.0\" \/>\n\n <link rel=\"stylesheet\" href=\"https:\/\/cdn.jsdelivr.net\/npm\/swiper@11\/swiper-bundle.min.css\" \/>\n <script src=\"https:\/\/cdn.jsdelivr.net\/npm\/swiper@11\/swiper-bundle.min.js\"><\/script>\n\n <style>\n :root {\n --scaler-primary: #1a56db;\n --scaler-primary-dark: #1e429f;\n --scaler-primary-light: #e1effe;\n --scaler-accent: #f97316;\n --scaler-bg: #f8fafc;\n --scaler-card-bg: #ffffff;\n --scaler-text-primary: #0f172a;\n --scaler-text-secondary: #64748b;\n --scaler-text-muted: #94a3b8;\n --scaler-border: #e2e8f0;\n --scaler-shadow: 0 4px 6px -1px rgb(0 0 0 \/ 0.07), 0 2px 4px -2px rgb(0 0 0 \/ 0.07);\n --scaler-shadow-lg: 0 20px 25px -5px rgb(0 0 0 \/ 0.08), 0 8px 10px -6px rgb(0 0 0 \/ 0.08);\n --scaler-radius: 0;\n --scaler-radius-sm: 0;\n }\n\n * { box-sizing: border-box;
