Use long long int instead of int and you get AC

The input begins with two positive integers n k (n, k<=10^7). The next n lines of input contain one positive integer ti, not greater than 10^9, each, thatâ€™s why you require long long int.

You didnâ€™t used nextInt() to get Fast input.

Then what was the use of writing that class FastRead??
