2 13 15 8
3 14 7
4 6
5
this pattern is right side
Thank You
Admin should ideally be tagged for CodeChef related things, like feedback on the website, feature requests, suspected wrong test cases in a problem, etc.
thank you

can you please reduce the time complexity of this code?
Hey @aarushiagarwal 
,
Could you please tell us what exactly your code is doing.Also Your code’s time complexity is already O(nlogn) but space complexity can be optimized.
yes, my code was submitted. thanks for your time
