Respected sir, I have doubt that you just type return sum(arr) and how you got congratulation because you not metioning formula, declare variables with list of array and etc.... or it happens automatically.

[anmoldhawan]

in first Question also, you right one line code and you got output? uou have not declare var or giving values, formulas? all hape automatically

[Peterin]

what will be the time complexity if we use sum()

[u]

this is the code i coded for simple sum array in hacker rank but it failed all test cases in submitting code but individually it compiled succesfully on passing arguments . that is automatically not passing test cases while succesful in manual entry

[siddhantjain]

is editorial option where we can find solution of a problem deleted in hackerrank 2022?? there is no option of editorial with problem now

[NadeemKhan-iwow]

broh its good nice but you have used sum() i.e. inbuilt function instead of that you should pinned the comment and write customize sum function by which things get clear.
