was doing coin change problem as an assignment(didnt know before), after came with this solution i checked the solutions available couldnt find a similar one like this, just curious. removing the element from the list is O(N) so seems this also O(N^2) right?

def rec_coin(target,coins):
    if target == 0 or coins == []:
        return 0

    max_coin = max(coins)
    mod = target % max_coin
    coin_count = (target-mod)/ max_coin

    return int(coin_count) + rec_coin(mod, coins)

    $\begingroup$ See cs.stackexchange.com/q/23593/755 for how you can solve it yourself. We can't tell you how long it takes to remove an element from a list, because that depends on the programming language and how the list is implemented (as a linked list? balanced binary tree? hashtable?); coding and language-specific questions are off-topic here. $\endgroup$ – D.W.
