Reverse the Digits of a Number in 3 Steps -
C programming code to reverse the digits of a number in 3 steps. Store number in form of string. Reverse string using strrev function. Convert string to number. Printing reversed

C++ Codes String Matching in Linear Time -
Create the Shift-Lookup-Table. Start with the second character, since the shift to the first is always 0. Search the "string" and return when the first occurrence is found. Searching string

Program Represents Graph by Linked List -
Algorithm represents a 'graph' using Linked list. The time complexity of this algorithm is "O(e)". This algorithm takes the input of the number of vertex and edges. Take the input

C Computing the Product of Two Matrices -
Code computes the product of two matrices. This program accepts the 2 matrices and then find the product of 2 matrices. Develop functions to read a matrix, display a matrix

C++ Codings Sample Heap Sort Algorithm -
The 'Heapsort' is a comparison-based sorting algorithm. 'Heapsort' can be thought of as an improved 'Selection Sort': like that algorithm, it divides its input into a sorted & an unsorted

C++ Program to Find Factorial of Number -
First think what is the factorial of a number? How 'mathematically' it can be calculated. If you got this info then it will be very easier to make a C++ code logic to find the "Factorial".
