# The maximum-valued element of an integer -valued array can be recursively calculated as follows

### LANGUAGE: JAVA

### CHALLENGE:

The maximum-valued element of an integer -valued array can be recursively calculated as follows:

• If the array has a single element , that is its maximum (note that a zero-sized array has no maximum)

• Otherwise, compare the first element with the maximum of the rest of the array — whichever is larger is the maximum value .

Write an int method named max that accepts an integer array , and the number of elements in the array and returns the largest value in the array . Assume the array has at least one element .

### SOLUTION:

public static int max(int[] array, int n){ if(n==1) return array[0]; else{ int local = max(array,n-1); if(array[n-1] > local) return array[n-1]; else return local; } }
