Problem 1 (4.5 points) Algorithm REXALG is a recursive algorithm that takes in an array of size n and makes two recursive calls of size n - 1, one call of size n - 2, and it takes O(n) for all of its non-recursive code. It has base cases of n= 1 and n=0. Give a recurrence and draw a recurrence tree for Algorithm REXALG. Note that you do not need to evaluate the complexity of this recurrence
