INTEST - Enormous Input Test

no tags 

The purpose of this problem is to verify whether the method you are using to read input data is sufficiently fast to handle problems branded with the enormous Input/Output warning. You are expected to be able to process at least 2.5MB of input data per second at runtime.


The input begins with two positive integers n k (n, k<=107). The next n lines of input contain one positive integer ti, not greater than 109, each.


Write a single integer to output, denoting how many integers ti are divisible by k.

Just optimized my code from 2.04 to 0.48s !
Keep learning new things and applying them in your code!

@invisible1997 it also depends on the programming language you are using. Like C,C++ are very close to the machines as compared with Python and Java, programs in C++ and C executes faster than others plus your code also matters what's your time complexity.

Was able to get performance down to 1.54 secs using mod operator PYTHON3

2.33 in python using stdin/stdout. Using input() will not pass. Which method is faster than stdin/stdout?
