Backtracking Algorithm Interview Questions Last Updated : 22 Sep, 2025 Comments Improve Suggest changes 53 Likes Like Report Backtracking is a powerful algorithmic technique used to solve problems by exploring all possible solutions in a systematic and recursive manner. It is particularly useful for problems that require searching through a vast solution space, such as combinatorial problems, constraint satisfaction problems, and optimization tasks.Easy ProblemsRat in a MazePrint all permutationsPalindromic Partitions All possible paths in a matrixSubset sumTug of warMedium ProblemsN Queens ProblemWord Break ProblemPath to middle cell in a mazeHamiltonian cycleSudokuM Coloring Problem Cryptarithmetic puzzlePath of more than k length Partition into k subsets Hard ProblemsWarnsdorff's AlgorithmRemove Invalid ParenthesisMatch a pattern and string using regular expressionlongest possible route in a matrix with hurdlesShortest safe route in a path with landminesRelated Links:DSA TutorialSystem Design Tutorial GfG 160DSA 360° Create Quiz Comment K kartik 53 Improve K kartik 53 Improve Article Tags : Backtracking DSA Interview Questions interview-preparation placement preparation Interview-Questions +2 More Explore DSA FundamentalsLogic Building Problems 2 min read Analysis of Algorithms 1 min read Data StructuresArray Data Structure 3 min read String in Data Structure 2 min read Hashing in Data Structure 2 min read Linked List Data Structure 2 min read Stack Data Structure 2 min read Queue Data Structure 2 min read Tree Data Structure 2 min read Graph Data Structure 3 min read Trie Data Structure 15+ min read AlgorithmsSearching Algorithms 2 min read Sorting Algorithms 3 min read Introduction to Recursion 15 min read Greedy Algorithms 3 min read Graph Algorithms 3 min read Dynamic Programming or DP 3 min read Bitwise Algorithms 4 min read AdvancedSegment Tree 2 min read Binary Indexed Tree or Fenwick Tree 15 min read Square Root (Sqrt) Decomposition Algorithm 15+ min read Binary Lifting 15+ min read Geometry 2 min read Interview PreparationInterview Corner 3 min read GfG160 3 min read Practice ProblemGeeksforGeeks Practice - Leading Online Coding Platform 6 min read Problem of The Day - Develop the Habit of Coding 5 min read Like
