Web7 okt. 2024 · Merge sort is a divide and conquer algorithm. It is a recursive algorithm. In merge sort, we have to divide the container (container can be an array, list, etc.) into two halves, then we will call merge sort recursively on the two halves. WebNow we have to figure out the running time of two recursive calls on n/2 n/2 elements. Each of these two recursive calls takes twice of the running time of mergeSort on an (n/4) (n/4) -element subarray (because we have to halve n/2 n/2) plus cn/2 cn/2 to merge. We have two subproblems of size n/2 n/2, and each takes cn/2 cn/2 time to merge, and ... elba alias agent john luther
