Given a 2D array of letters, return whether a given word can be found in the grid. To make a word, you can use any adjacent character next to the character you're currently on in the word. But you cannot use the same grid index twice i.e. in a 2x2 array, you could find a 4 letter word by visiting each letter once

Given an array of integers, return true if there are contiguous numbers such that they add up to a specific target. For eg: [6,1,2,3,3,7] target sum is 8, will return true because 2,3,3 adds up to 8 and are contiguous. [6,1,2,4,3,3,7] will return false as there are no contiguous elements which adds up to 8.
