Yesterday my coach give me a hard problem "a + b".

In standard input gives two numbers a and b.

I must output sum a + b.

Please help me with this hard problem

UPD: YEE, I KNOW HOW TO SOLVE!

import time

a, b = map(int, input().split())
start = time.time()
time.sleep(a)
time.sleep(b)
print(time.time() - start)
