(a) Find the complexity of the function used to find the kth smallest integer in an unordered array of integers. (20 points) int selectkth (int a[], int k, int n){ int i, j, mini, tmp; for (i = 0; i <k; i++) { mini = i; for (j i+1; j<n; j++) if (a[i]<a [mini]) mini = j; = tmp = a[i]; a[i] = a[mini]; a [mini] = tmp; } return a[k1]; } (b) If we assume that the input array is always sorted, how can we rewrite the above function to return the kth smallest element of the sorted array? What would be the running time complexity in that case?(10 points) (a) Find the complexity of the function used to find the kth smallest integer in an unordered array of integers.
