A palindrome program in C checks whether a number reads the same forwards and backwards. Numbers like 121, 1331, and 12321 are palindromes; 12345 is not. The standard technique is to reverse the digits and compare with the original. This page covers three versions: a simple iterative solution, a clean function-based version, and a recursive …
Converting a binary number to decimal, octal, and hexadecimal in C demonstrates how the same bit pattern can be expressed in different bases. Binary uses base 2, decimal uses base 10, octal uses base 8, and hexadecimal uses base 16. Once you have the decimal value, C’s printf format specifiers (%o and %X) handle octal …
The subset sum problem asks: given a set of integers and a target sum, find all subsets of the set whose elements add up to the target. It is a classic application of backtracking — a systematic method that builds candidates incrementally and abandons a partial candidate (“prunes”) as soon as it determines the candidate …
Depth First Search (DFS) is a graph traversal algorithm that explores as far as possible along each branch before backtracking. Starting from a source node, it follows one path all the way to a dead end, then backtracks and tries the next unvisited neighbor. DFS uses a stack — either an explicit one or the …
Breadth First Search (BFS) is a graph traversal algorithm that explores nodes level by level — starting from a source, it visits all immediate neighbors first, then their neighbors, and so on. Because of this level-by-level behavior, BFS always finds the shortest path in an unweighted graph. It is used in GPS navigation, social network …
C Program to find the Inverse of a Matrix. To find the Matrix Inverse, matrix should be a square matrix and Matrix Determinant is should not Equal to Zero. if A is a Square matrix and |A|!=0, then AA’=I (I Means Identity Matrix).
