Oct 5, 2012 · If we do test to see if one side is zero, each time the recursive call to multiply is made, the code must evaluate the expression; however, if we do not test for equals zero, then the code adds a bunch of zeros together n number of times. In reality, both methods "weigh" the same - so, to save memory, I leave out the code.

Mar 11, 2016 · your recursive funtion mult gets called b number of times. And at each time, you call the function you accumulate a to the returned value. So you basically add a b number of times, hence resulting in the a*b. I would suggest you store change the line : return a + mult(a, b - 1); to. int temp = a + mult(a, b - 1); return temp

Apr 18, 2013 · Write (and provide a tester for) a recursive algorithm: int multiply(int x, int y) to multiply two positive integers together without using the * operator.
