The purpose of the compare function is to define an alternative sort order. The compare function should return a negative, zero, or positive value, depending on the arguments: function(a, b){returna - b} When thesort()function compares two values, it sends the values to the compare functi...
Write a C program to merge two sorted array elements into a single array.Problem Solution1. Create two arrays of some fixed size and define their elements in sorted fashion. 2. Take two variables i and j, which will be at the 0th position of these two arrays. 3. Elements will be ...
