Hey guys I'm a high school student taking a AP Computer Science class and I'm kinda confused on some things. What I'm confused on is what the % is used for in lines 43 and 54?

Many languages (such as Java) use the percentage symbol as the modulo operator: the remainder from the division of the first number by the second.

In this case it is used to figure out witch foot needs to be moved: if stepsCount is even (remainder of the division by 2 equals 0) move the leftFoot, otherwise move the right one.
