add line 53
this prevents -ve indexed from being access

the run time error was because -1 index was being accessed

#3

@chhavibansal the code is running fine after adding this condition but I am getting WA on SPOJ

#4


refer to this

#5

@chhavibansal i cannot figure out the difference between the 2 codes. The one you provided is running without that condition, and it got AC too. Please help me figure out what is wrong with this code

just a minor update
i - m>= 0

see

in my code there are situations where -1 index is being accessed , it is a bad practice to access -ve indexes but here in the code ( my code) the -ve index is accessed without giving runtime error
but the memory allocation for ur code might be such that the access is not possible hence the additional check is required that -ve index are not accessed

@Ishitagambhir

@chhavibansal thank you so much, my code got accepted. :slight_smile:
