An array of ints , arr, has been declared and initialized . Write the statements needed to reverse the elements in the array . So, if the elements were originally 5, 13, 4, 97 then after your code executes they would be 97, 4, 13, 5.

CHALLENGE:

An array of ints , arr, has been declared and initialized . Write the statements needed to reverse the elements in the array . So, if the elements were originally 5, 13, 4, 97 then after your code executes they would be 97, 4, 13, 5.

SOLUTION:

int k, temp;
for (k = 0; k < arr.length/2; k++) { 
    temp = arr[k]; 
    arr[k] = arr[arr.length-1-k]; 
    arr[arr.length-1-k] = temp; 
}
