My basic python template for fast IO, source: https://stackoverflow.com/questions/22623528/sys-stdin-readline-and-input-which-one-is-faster-when-reading-lines-of-inpu

template.py

import sys
input = sys.stdin.readline

# Function to read an int
def read_int():
    return int(input().strip())

# Function to read a list of integers
def read_int_list():
    return list(map(int, input().split()))

# Function tod read a single string
def read_string():
    return input().strip()

# Function to read a list of strings
def read_string_list():
    return input().split()
  
def solve():
    pass
    return 0

def main():
    t = read_int()
    while t > 0:
        print(solve())
        t-=1

if __name__ == "__main__":
    main()
