Write a method fill up an array of size n - and returns the array to the
caller - with the following conditions
1. the numbers shud be between 0 to n-1
2. no repeated numbers
3. the method should have a deterministic time to fill the arrays
4. arrays returned from the method should have
=Take a function rand() which returns value between [0, 1) uniformly or use
function rand(n) = n*rand() which return value between 0- (n-1) using
uniform probability distribution.
=Now create a array A[0..n-1] = [0..n-1]
now rake an array R.
k = n;
for(i = 0; i n; i++){
a = rand(k);
