(a) Find the complexity of the function used to find the k-th 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[k-1]; } (b) If we assume that the input array is always sorted, how can we rewrite the above function to return the k-th 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 k-th smallest integer in an unordered array of integers.
