In various codes where time limit exceeded, by using while(t-- >0) instead of while(t--) code runs successfully. I don't know about while(t-- >0) , I read it somewhere in the codechef examples solution.

It's different if `t` can be negative. – interjay Apr 25 '21 at 14:57

The (inexistent) difference should not matter for "time limit exceeded". Something other is the reason for failing or not. – pmg Apr 25 '21 at 14:57

In practice, they are equivalent. It's just a matter of taste. Some think that while(t-- > 0) is clearer than while(t--).
As long as t is not negative, the two are completely equivalent. But on the other hand, a negative t would most likely indicate a bug with a loop like that.
