why is this error coming?
when I am putting the input:4000000
output is coming:runguard: warning: timelimit exceeded (wall time): aborting command
runguard: warning: command terminated with signal 15

Hey @aaliyah_beg
Because Its not meeting time constraints of ur code :slight_smile:
i.e why u are getting TLE

#3

sir what is the time limit of any code?

#4

So See Its mentioned with the question what should be the max time limit
Most of the times it will be 1second
In 1second u can do 10^8 operations

Say if u are running a loop for n then its taken as n operations assuming u are not doing simple arithmetic inside

You will learn about Time complexity of code,if u haven’t till now

#5

Sir what do you mean by mentioned with the question , are you trying to say its different for different codes

#6

There are 2 things
Time complexity
&
Time Limit

Time complexity is of code , that’s what u are writing ,u will learn about it in the course.
Say if we have one for loop
for(int i=0;i<n;i++) then its complexity is O(n) i.e it need n operations
Every code has its own time complexity

Time Limit is of question ,accoding to which u decide what should be complexity of ur code .

Here this is a snapshot of some codechef problem , see time limit is mentioned as 1second.
Every question has its own time limit

okay sir, got it. THANK YOU!
