PROGRAMMINGSIDE

Write a function to insert node or element at the beginning of linked list. C Program to insert node or element at the beginning of linked list.

C program for binary search: Binary search works only in sorted array. Prerequisite of binary search is that array should be sorted. If you want to implement binary search in unsorted array then you should sort array using any sorting algorithm like merge sort, quick sort etc and then implement binary search.

Bubble sort in c: Bubble sort is the simplest algorithm for sorting elements of array. We can sort elements in ascending and descending order using bubble sort algorithm.

Simple C program to rotate matrix by 90 degrees.

A array is given and sort it in the wave form. Wave form of a array: If array is {1,4,2,7,8,4,9,3} then sort it like {4,1,7,2,8,4,9,3}. Like arr[0]>=arr[1]<=arr[2]>=arr[3]<=arr[4]....

You are given a matrix arr[m][n] then print it in the wave form as given in the image.

Simple C Program to check palindrome string or whether string is palindrome or not: To check palindrome, declare a variable flag and initialize it to 1 and then compare first element with last element then second element with second last element and so on.
