The mode method below is intended to return the mode, which is the most frequently occurring value in its integer array parameter arr. For example, if arr contains {6, 5, 1, 5, 2, 6, 5}, the method should return 5.

/** Precondition: arr.length >= 1 */
public static int mode(int[] arr)
{
    int modeCount = 1;
    int mode = arr[0];
    
    for (int j = 0; j < arr.length; j++)
    {
        int valCount = 0;
        for (int k = 0; k < arr.length; k++)
        {
            if ( /* missing condition 1 */ )
            {
                valCount++;
            }
        }
        if ( /* missing condition 2 */ )
        {
            modeCount = valCount;
            mode = arr[j];
        }
    }
    return mode;
}

Which of the following can be used to replace /* missing condition 1 */ and /* missing condition 2 */, respectively, so that the method works as intended?
