Question

Using java, write a method called findSmallestEven() that receives a 2-dimentional array of integers as a parameter and returns the smallest even number contained within it. [Note: Any hardcoded return value will not be accepted]

Answer 1

public static int findSmallestEven(int[][] arr) {
    boolean found = false;
    int min = arr[0][0];
    for (int i = 0; i < arr.length; i++) {
        for (int j = 0; j < arr[i].length; j++) {
            if (arr[i][j] % 2 == 0) {
                if (!found || arr[i][j] < min) {
                    found = true;
                    min = arr[i][j];
                }
            }
        }
    }
    return min;
}
