WebThe important part of the merge sort is the MERGE function. This function performs the merging of two sorted sub-arrays that are A [beg…mid] and A [mid+1…end], to build one sorted array A [beg…end]. So, the inputs of the MERGE function are A [], beg, mid, and end. The implementation of the MERGE function is given as follows -. WebRadix sort is a sorting algorithm that sorts the elements by first grouping the individual digits of the same place value. Then, sort the elements according to their increasing/decreasing order. Suppose, we have an array of 8 elements. First, we will sort elements based on the value of the unit place. hrswg360.secowarwick.comWeb28 mrt. 2024 · Wrap merge_sort () in a function timed_merge_sort () which starts the clock, runs the merge_sort () and then stops the clock and prints the results.
