Logic Building Problems Last Updated : 08 Sep, 2025 Comments Improve Suggest changes 72 Likes Like Report Logic building is about creating clear, step-by-step methods to solve problems using simple rules and principles. It’s the heart of coding, enabling programmers to think, reason, and arrive at smart solutions just like we do.Here are some tips for improving your programming logic: Understand the problem: Read and understand the problem statement. Generate Examples: Create additional input and output cases for each problem. Draw observations: Draw observations and patterns based on the examples you created. Start with Basic: First, think of the basic way to solve the problem then optimize the solution.Concepts Maths for Computer ScienceBasic ProblemsCheck Even or OddMultiplication TableSum of Naturals Sum of Squares of Naturals Swap Two NumbersClosest NumberDice Problem Nth Term of AP Easy ProblemsSum of Digits Reverse Digits Prime Testing Check PowerDistance between Two PointsValid TriangleOverlapping RectanglesFactorial of a Number Pair Cube CountGCD or HCFLCM of Two NumbersPerfect NumberAdd Two Fraction Day of the Week Nth Fibonacci Number Decimal to BinaryN-th term of 1, 3, 6, 10, 15, 21…Armstrong NumberPalindrome NumberDigit RootMedium ProblemsSquare Root3 DivisorsDivisible by 4 Divisibility by 11Divisibility by 13 K-th Digit in a^bFraction to Recurring DecimalRecurring Sequence in a Fraction Compute nPr Compute nCr Pascal’s Triangle All Factor (Or Divisors)Prime FactorizationLargest Prime factorModular Exponentiationnth Catalan NumberBinomial CoefficientPower SetNext PermutationHard ProblemsSieve of Eratosthenes Super PrimeClock Angle ProblemTower of HanoiRat and Poisoned8 puzzle Problem Euler's Totient FunctionJosephus Problem Recommended LinksTop Logic Building Interview Problems Practice Logic Building ProblemsPattern Printing ProblemsMathematical Algorithms Comment D diwakar_mandal Follow 72 Improve D diwakar_mandal Follow 72 Improve Article Tags : DSA logical-thinking 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
