# Problem in World Cup lab 6 with the variable N?

for some reason when i increase the no of N my code just doesn't work and check50 returns errors in men's world cup and women's world cup. Pls help me

• if you make N too big, it causes the program to timeout in check50. what exactly is your issue, what N ranges are you trying. what is your output. what do you expect. for very small N the results can be wild, as N increases the results should approach the ratings. Commented Mar 10 at 19:43
• Please clarify your specific problem or provide additional details to highlight exactly what you need. As it's currently written, it's hard to tell exactly what you're asking.
