Merge sort

Merge Sort recursively sorts a given collection of numbers or elements by using the divide and conquer strategy in less time. It is one of the most used algorithms, with the worst-case time complexity of O (n log n). It was invented by John Von Neumann. The algorithm continuously divides an array into sub-arrays until each sub-array consists of a single element. It then merges those sub-arrays to produce a sorted array.

Provide correct and typing answer.

Consider the following C++ code fragment for Selection Sort (the numbers on the left-hand side
are line numbers).
void selectionSort(int arr[], int n) {
int i, j, min;
1
for (i = 0; i<n; i++) {
2
min = i;
// current minimum is first unsorted element
// find index of minimum element
for (j=i+1; j<n; j++) {
if (arr[j] < arr[min]) {
min = j;
}
}
// swap minimum element into place
swap(&arr[i], &arr[min]);
}
}
