    how did you inforce the requirements given in q4, I understand the inversions added due to relative ordering? I feel the prefix of permutation changes when adding elements so not sure how you are handling that.

  • @numb3r5
    @numb3r512 күн бұрын

    Yes, the prefix of permutation changes, but the relative ordering of the prefix does not change - and the number of inversions of any prefix is only dependent on the relative ordering of the elements

    its so nice how you code both c++ and python, i have only one of those languages in my class do you think i should bother learning second one as someone inexperienced or master one of them first? (sorry for bad low level question)

  • @neymarfan4023

    I think knowing both helps. Python is better in dealing with string questions/bigger numbers while in general CPP is much faster and most prefered by cpers.

    Out of curiosity... Did you not apply to MIT, Harvard, Stanford or any of the top engineering schools in the states? I looked at your bg and there's no way you didn't get accepted. The only reason I could think of was either you didn't apply or you didn't want to study in the US....
