Identify the body of a function
In Twenty-One, it is useful to have a function that determines the maximum of two competing players' hands. For example, imagine a scenario where playerA and playerB have the following hands:
playerA:queenDiamonds,threeClubs,aceHearts(worth 1),fiveSpadesplayerB:kingHearts,jackHearts
Below is a simple version of that function, called maxHand, that ignores whether or not the hand busts. It also has an if/else expression, which you will learn how to write in an upcoming lesson.
def maxHand(handA: Int, handB: Int): Int = {
if (handA > handB) handA
else handB
}
In the previous video, the body of the function was emphasized as the only part of a function that you need to know for this course. What is the body of the maxHand function?
