Return an array of two integers, where the first element is the total weight of team 1, and the second element is the total weight of team 2 after the division is complete. codesignal codesignal-solutions codesignal-arcade codesignal-interview . A minor comment: if you've ever worked with multilingual applications. .strip(): Normally .strip() is chained at the end of a string where the data can have extraneous spacing, but this one is your own string.

(I've taken the liberty of converting all identifiers to PEP8 style.). Thank you in advance. Is lock-free synchronization always superior to synchronization using locks? minesweeper1 = mainarray => // an arrow function, that gets the two d array passed !mainarray.some ( (row,rownumber) => row.some ( (field,columnumber) =>//checking the 2d array if some of the fields field //and the magic recursive function is true d-- ? All possible sums of 2 consecutive elements are: [input] array.integer inputArray A character which is either a digit or not. Do read comments as they explain a lot and also every block of code. So, this implies two things: one, the class should probably have a different name (e.g. This is not a code review site, so this question is off-topic, but your solution is not bad.
