Logic Building Problems Last Updated : 09 Jun, 2025 Comments Improve Suggest changes Like Article 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.Basic 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 EratosthenesClock Angle ProblemTower of HanoiRat and Poisoned8 puzzle ProblemDeterminant of a MatrixEuler's Totient FunctionJosephus ProblemRecommended LinksTop Logic Building Interview Problems Practice Logic Building ProblemsPattern Printing ProblemsMathematical Algorithms Comment More infoAdvertise with us Next Article Logic Building Problems D diwakar_mandal Follow Improve Article Tags : DSA logical-thinking Practice Tags : logical-thinking Similar Reads IBM Placement Paper | Logical Reasoning Set - 5 This is an IBM model placement paper on Logical Reasoning for placement preparation.
