Question

Consider the following two sum functions:
def sum_iter(x: int) -> int:
result: int
while x >= 0:
result += x
x -- 1
return result
versus
def sum_recur(x: int) -> int:
if x < 0:
return 0
else:
return x + sum_recur(x - 1)

Which of the following function calls requires the least memory (as would be visible in a
memory diagram) to process? If multiple are tied, select each.
sum_recur(1)
sum_recur(10)
sum_recur(100)
sum_iter(1)
sum_iter(10)
sum_iter(100)

Each turn, a player repeatedly rolls a die until either a 1 ("pig") is rolled or the player holds and scores the sum of the rolls (i.e. the turn total). At any time during a player's turn, the player is faced with two decisions: roll - if the player rolls 1: the player scores nothing and it becomes the opponents turn. 2 - 6: the number is added to the player's turn total and the player's turn continues. hold - The turn total is added to the player's score and it becomes the opponent's turn.
