5. Implement the following 3 sorting algorithms in C programming (Note: Please provide an interface for user to input a sequence of integers (at most 100 integers) separated with space, i.e., the input is like "12 5 8 45 93 1365 38 37, choose the algorithm to sort, and output the final sorted result on screen.): a) Shell Sort using the increments (1, 3, 7}; b) Merge Sort; c) Quick Sort with median-of-three pivot selection, the partitioning strategy and a cut-off of 3 (along with the Insertion Sort)
