I wrote this code for https://leetcode.com/explore/challenge/card/december-leetcoding-challenge/569/week-1-december-1st-december-7th/3556/ in typescript and when i use "run code" it says my output matches the input with In : [0] Out [0,#] Expected [0,#] but when i do "submit code" and it runs the same test it says it fails with In : [0] Out [0] Expected [0,#]
