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 -. WebMar 21, 2024 · Here are the steps to sort the given items in ascending order using Bubble Sort: Start with the first two elements, compare them, and swap if necessary.
