It became TLE when I confirmed the operation with the print function in the competition pro

example

I actually noticed this in the following AtCoder problem: https://atcoder.jp/contests/abc162/tasks/abc162_c I was turning a 200 * 200 * 200 for statement.

problem

The output was done with the print function to check the operation.

Code in question

I am using the time module for time measurement.

import time
import math
k=int(input())
stat = time.time()
k+=1
ans=0
for i in range(1,k):
    for j in range(1,k):
        for z in range(1,k):
            print(i,j,k)
            print(math.gcd(math.gcd(i,j),z))
            ans+=math.gcd(math.gcd(i,j),z)
end = time.time()
print(ans)
print(end-stat) 
##k=10  =>  0.0718231201171875(s)
##k=100 => 20.816463232040405(s)

Code without print function

import math
import time
k=int(input())
start = time.time()
k+=1
ans=0
for i in range(1,k):
    for j in range(1,k):
        for z in range(1,k):
            ans+=math.gcd(math.gcd(i,j),z)
end = time.time()
print(ans)
print(end-start)
#k=10  => 0.0009169578552246094(s)
#k=100 => 0.4900369644165039(s)

Conclusion

It seems that it takes a lot of time if print also overlaps. First try it while printing a little (k = 10 this time) You must comment out when calculating time-consuming orders.
