  • Time limit: 1.00 s
  • Memory limit: 512 MB

A factory has n machines which can be used to make products. Your goal is to make a total of t products.

For each machine, you know the number of seconds it needs to make a single product. The machines can work simultaneously, and you can freely decide their schedule.

What is the shortest time needed to make t products?


The first input line has two integers n and t: the number of machines and products.

The next line has n integers k_1,k_2,\dots,k_n: the time needed to make a product using each machine.


Print one integer: the minimum time needed to make t products.


  • 1 \le n \le 2 \cdot 10^5
  • 1 \le t \le 10^9
  • 1 \le k_i \le 10^9
