a methodcalledcompareArraysthat takes two arrays of integers (iA1 and iA2) as parameters and returns an array of boolean or a null value. If either iA1 or iA2 is null, the method has to return a null value.

The returned boolean array has the same length as iA1. Its i-th element is true if the i-th element of iA1can be found anywhere in iA2 and false otherwise.

Be efficient i.e. do not continue to look for a String once you have found it.
