#1

Hey Rahul, update your code’s line:19 like this while(q-->0)

#3

@sanjeetboora Faced the same issue, my question is HOW DOES THAT WORK? doesn’t while loop stop when q-- automatically reaches zero?

#4

Hey Lakshay, yes that’s right while loop stop when q-- automatically reaches zero from a positive number because in C++ 0 is treated as false, but it will leads to an infinite loop if q is negative because in C++ -ve is treated as true and q-- will never reach 0 then.
