[LeetCode] Jump Game

bool canJump(int A[], int n) {int lastIndex = n - 1;int index = n - 1;while (index >= 0){if (A[index] >= (lastIndex - index)){lastIndex = index;}index--;}if (lastIndex == 0){return true;}else{return false;}}

bool canJump(int A[], int n) {int canJumpPosition = n - 1;int curPosition = n - 1;while (curPosition >= 0){if ((canJumpPosition - curPosition) <= A[curPosition]){canJumpPosition = curPosition;}curPosition--;}if (canJumpPosition == 0){return true;}else{return false;}}
