WebDeveloping a recursive function. We begin by developing a surprisingly short and simple recursive function to determine whether the values in an integer array can be placed into two bags so that the sums of the values in the two bags are equal. Two examples: For the array {2, 2}, put the first 2 in one bag and the second 2 in another; the ... WebThe idea for the solution: Recursion and Backtracking We can describe the idea for the solution as follows: Represent the maze as a bidimensional array (or a list of lists). Define one character to state that the room is empty and another for rooms that someone cannot go through. There are four possible moves: forwards, backwards, left and right. cheryl lowe grande prairie
