Alice and Bob play a coin-toss game. Each entry in `aList` is `[i, j]`, where `i` is Alice's outcome and `j` is Bob's outcome. Procedure `findWinner(aList)` should return `c`: `0` for Bob, `1` for Alice, and `2` for a draw. Which procedure correctly identifies the winner?

A

``` Procedure findWinner(aList) alice_sum = 0 bob_sum = 0 c = 3 foreach toss in aList { if(first(toss) == "H") { alice_sum = alice_sum + 1 } else { bob_sum = bob_sum + 1 } } if(bob_sum < alice_sum) { c = 1 } else { c = 0 } return(c) End findWinner ```

B

``` Procedure findWinner(aList) alice_sum = 0 bob_sum = 0 c = 2 foreach toss in aList { if(first(toss) == "H") { alice_sum = alice_sum + 1 } if(last(toss) == "H") { bob_sum = bob_sum + 1 } } if(bob_sum > alice_sum) { c = 0 } if(bob_sum < alice_sum) { c = 1 } return(c) End findWinner ```

C

``` Procedure findWinner(aList) alice_sum = 0 bob_sum = 0 c = -1 foreach toss in aList { if(first(toss) == "H") { alice_sum = alice_sum + 2 } if(last(toss) == "H") { bob_sum = bob_sum + 2 } } if(bob_sum > alice_sum) { c = 0 } if(bob_sum < alice_sum) { c = 1 } else { c = 2 } return(c) End findWinner ```

D

``` Procedure findWinner(aList) alice_sum = 0 bob_sum = 0 c = -1 foreach toss in aList { if(first(toss) == "H") { alice_sum = alice_sum + 1 } else { bob_sum = bob_sum + 1 } } if(bob_sum < alice_sum) { c = 0 } if(bob_sum > alice_sum) { c = 1 } else { c = 2 } return(c) End findWinner ```
