Consider the following code: void Start() { for (int i = 0; i < 10; i++) { if (i < 5) { Debug.Log("X"); } else { Debug.Log("Y"); } } } How many times will the characters X and Y be printed to the Console?

• 5 X's and 5 Y's

• 0 X's and 10 Y's

• 4 X's and 6 Y's

• 6 X's and 4 Y's

5 X's and 5 Y's will happen since you need to consider index 0 in the if statement condition.

• Entry

• LongJump
