The shellsort algorithm is described in detail in the Topic 4 lecture slides, as well as Wikipedia (https://en.wikipedia.org/wiki/Shellsort). Write a function in C which implements the shell sort algorithm. The recommended approach is to create an array of sub arrays using dynamic memory allocation, sort those sub-arrays, and replace them in the array. This is achievable through the use of double pointers. The following may be helpful: https://www.geeksforgeeks.org/dynamically-allocate-2d-array-c/ Inputs: array -> a pointer to the integer array to be sorted...
