In this blog post, we learn how to write a C program to search an element in a sorted and rotated array? So here we will write a C program to search an element in a sorted and rotated array. Suppose an array ( ‘arr’ ) sorted in ascending order is rotated at some pivot […]

In this blog post, we learn how to write a C program to rearrange array such that elements at even positions are greater than odd? So here we will write a C program to rearrange array such that elements at even positions are greater than odd. Suppose ‘arr’ is an integer array of size N

In this blog post, we learn how to write a C program to remove duplicates from sorted array? So here we will write a C program to remove duplicates from sorted array. Suppose ‘arr’ is a sorted integer array of size N and task to remove the duplicates elements from the array in such way

In this blog post, we learn how to write a C program to find a contiguous subarray which has the largest sum and returns its sum? So here we will write a C program to find the sum of contiguous subarray within a one-dimensional integer array which has the largest sum. We will also see

In this blog post, we learn how to write a C program to double the first element and move zero to end for a given array? Here we are supposing that for a given array of n integers ‘0’ is an invalid number and all others as a valid number. We need to convert the

In this blog post, we learn how to write a C program to move all negative numbers to the beginning and positive to end with constant extra space? So if an array of random numbers, push all the negative and positive numbers to the beginning and end of the array. We will also see how to

In this blog post, we learn how to write a C program to move all zeroes to end of array? So if given an array of random numbers, push all the zero’s of a given array to the end of the array. We will also see how to shift all zero’s of an array to

In this blog post, we learn how to write a C program to find all pairs of an integer array whose sum is equal to a given sum? So here we will write the C program to find all pairs of an integer array whose sum is equal to a given number. We will also
