In recent competitions, I came across this type of RUNTIME ERROR. Here's the thing:

I wrote a program like this:

def main():
    k = 15
    m = 3
    
    for a in range(k + 1):
        for b in range(k + 1):
            for c in range(min(m, k) + 1):
                for d in range(min(m, k) + 1):
                    continue
    return

t = 1
for _ in range(t):
    main() 

But in Atcoder, it showed something like this: (Sorry that the picture isn't clear enough)

It really bothered me and I wonder if anyone could be so kind as to help me with this issue.

(p.s. The RUNTIME ERROR doesn't show in Codeforces, so I'm really confused)

Here are some codes that don't show RUNTIME ERROR:

Code 1:

k = 15
m = 3

for a in range(k + 1):
    for b in range(k + 1):
        for c in range(min(m, k) + 1):
            for d in range(min(m, k) + 1):
                pass

Code 2:

def main():
    k = 15
    m = 3
    
    for a in range(k + 1):
        for b in range(k + 1):
            for c in range(min(m, k) + 1):
                for d in range(min(m, k) + 1):
                    print(d)
    return

t = 1
for _ in range(t):
    main()
