Can anyone please point out why am I getting TLE for subtask 2. I really don’t think it will exceed the time limit.

Can anyone please provide a test case for CodeChef: Practical coding for everyone and/or https://www.codechef.com/viewsolution/40537938? The testcases already given are all working I think.

If anyone have a Python Solution, please share it. I’m getting TLE for subtask 3. I used the approach mentioned above.

sarthakmanna · December 20, 2020, 8:49am

I am failing only 1 testcase… IDK why…

My approach:

Use a ordered Set and take the first and last pair (smallest and largest)…
if the first one fills completely, put back the second then print first.index+" "+ k+" "+first.index+" 0" and take care if first.val>k
else print first.index+" "+first.val+" "+second.index+" "+(k-first.val); and reduce the second.val and put it back
