2. The function f is defined for non-negative integers a and b recursively as follows: f (a, b) ={ if a = 0 or b = 0 f (a f (a f (а, а) + f (b — а, а) - 1) + 2a - 1 if a if a > b if a < b b b b, b) + f (b, b) Compute f (2, 3) by drawing a recursion tree showing all of the computation required and then use your tree to compute the answer.

2.
The function f is defined for non-negative integers a and b recursively as follows:
f (а, b) 3D1
if a = 0 or b = 0
f (a - 1, b
f (a
f (а, а)
1) + 2a - 1 if a
if a > b
if a < b
b
b, b) + f (b, b)
+ f (b
а,
а)
}
Compute f (2, 3) by drawing a recursion tree showing all of the computation
required and then use your tree to compute the answer.
