Given an n x m matrix where all of the units are 0s except for an 1
for “start”, a 2 for “end”, and 3s for walls, find the shortest paths 
that you can take to get from 1 to 2, while working around 3s.

Example:

let grid = [
[1,0,0],

Given two integer arrays of size n, return a new array of size n such that 
n consists of only unique elements and the sum of all its elements is maximum.

Example:

let arr1 = [7, 4, 10, 0, 1]
let arr2 = [9, 7, 2, 3, 6]

Given two strings n and m, return true if they are equal when both are entered into 
text editors. But: a # means a backspace character (deleting backwards), and a % means 
a delete character (deleting forwards).
