Question

when i am running the testcases its showing answer but when i am running it in codechef it is throwing me SGTSTP error.Where am i doing wrong?

#2

it’s an ongoing contest, so let me ask whether i should discuss in this platform?

#3

I am not asking algorithm here,while I was running this code in codechef I was getting sigtstp error
I wanted to know what it is and how to overcome it?
Though it was showing me the above error it got submitted correctly and why is that so?
