its time limit exceeded error because your solution runs slow . try to optimize

Code needs to be optimized by time or space or both.

its 1 loop code only…still showing tle

Fibeasy from sept challenge

loops doesnt matter
number of operations does
so we should do <=10^8 operations
(u can use as many loops as u can)

i too have nzec error in python

Common causes of NZEC error are out-of-bound memory access, un-initialized variables and not enough inputs. Check your code for all of these.
