Expert Solution

Step 1

Given Code:

32.

public static double foxtrot(ArrayList<Integer> list) {
double p = 0.0;

for (int item: list){
p += item;

double q = p / list.size();
return q;
}

33.

public static int waltz (ArrayList<Integer> list) {
int temp = list.get(0);

for (int k = 1; k < list.size(); k++)
if (list.get(k) < temp)
temp = list.get(k);

return temp;
}
