Q1: Given a 2 dimensional array of characters and a dictionary, extract all the meaningful words from the array. The words can be positioned horizontally, vertically or diagonally within the array. I was asked to come up with an efficient algorithm..
Q2: In a single nested for loop, determine if a filled in sudoku is a valid solution.
