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.

I am failing only 1 testcase… IDK why…

My approach:

  1. Use a ordered Set and take the first and last pair (smallest and largest)…
  2. 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
