# countFill
* input: `int[] nums`
* input: `int s`
Fill the given array with ints counting down from `s`.
```java
int []a = new int[6];
countFill(a, 80); // {80,79,78,77,76,75}
System.out.println(Arrays.toString(a));
```

# noSevens
`int noSevens(int[] nums)`
* Count how many sevens are in the array.
* Set all of them to zero.
* Return the number of sevens you find.
```
int[] ns = { 10,7,20,7,30,7,7,40};
int a = noSevens(ns);
String ans = Arrays.toString(ns);
System.out.println(a)
System.out.println(ans)

# countBetween23
`int countBetween23 (int[] nums)`
* Count how many numbers between a 2 and 3.
* Only one 2, one three.
* 2 appears before 3
```
int [] ns = {1,2,5,6,7,13,3,8}
System.out.println(countBetween(ns)); // 4
