similar to my solution but i removed 0 values with each pass and edit the list in place. Ultimately this solution is better for performance. However min-heap solutions are the best

Swear this is a trick question to see if people remember order of operations

Also to add, the statement before and after and provide either a true or false(Boolean) output, so when returned you get True or False

Time complexity is not factored into the challenge

Forget that Return itself always evaluates an expression

Whats the difference with formatting the variable as f"{40-mm}" and converting it to a string performance wise

Wizardry

Insane

Nice

not else!

No, that's what the array_keys($split) is for.

Does using $i as a seccondary variable in a function (function($item, $i)) automatically let array_map know this is referring to the array key?
