• If in a simple case you find that you're printing (visiting) the same element more than once, then its likely that you dont have a O(n) solution.

  • The problem is with the larger test cases where it suffers "Execution Timed Out" error. Could you elaborate how print statement would help here? Thanks!

  • How about adding some print statements to debug exactly what elements and indices you're looking at for a simple case?

  • Took me 2 evenings to solve this one and was really hard to get my head around. Suggest searching the web for "python function closure" as your next port of call.

  • Can someone please translate this for python? Thank you. I realised python is not there only after solving it lol.

  • Yeah, I did that! took some time to observe this though after first attempt(using itertools permutations) timed out on larger numbers.

  • As strings, '2000' comes before '11' and both have a weight of 2 in input "2000 10003 1234000 44444444 9999 11 11 22 123" but in answer they want '11' before '2000' and then '10003' before '22', and these logic contradicts each other!

    Could you explain how is the output correct?

    Got it! Where can I look for this fundamental concept? (i.e. how str(number) is ordered?, i.e. why '10003' <'22') Thanks!

  • For all asking, timeout during tests is not issue. There are few ways to simplify input data
