    // Write a static method called indexOf that takes an array of integers and
    // a value as parameters and that returns the index of the first occurrence
    // of the value in the array, returning -1 if not found

    // Write a static method called isUnique that takes an array of integers as
    // a parameter and that returns true if the values in the list are unique
    // and that returns false otherwise.  The values in the list are considered
    // unique if there is no pair of values that are equal.

    // Write a static method called runningSum that takes an array of integers
    // as a parameter and that returns a new array that contains the running
    // sum of the numbers in the array (where the i-th value of the new array
    // is the sum of the first i values of the original array)

    // Write a static method called rotateLeft that takes a nonempty array of
    // integers as a parameter and that rotates all values to the left by one
    // position, rotating the first value to the back of the array.  For
    // example, given the list {1, 2, 3, 4}, a call on rotateLeft should yield
    // {2, 3, 4, 1}.

    // Write a static method called rotateRight that takes a nonempty array of
    // integers as a parameter and that rotates all values to the right by one
    // position, rotating the last value to the front of the array (e.g., given
    // the list {1, 2, 3, 4}, a call on rotateRight should yield the list {4,
    // 1, 2, 3})
