The code below implements a function QU2 which has an input arr of type Array of Int and returns an integer. function QU2 (arr) { var i in Int var anInt in Int anInt <-- 0 for (i <-- 1 to 3) { if (AT (i, arr) > 6) then { } anInt <-- an Int + 1 return 2* an Int } (a) Trace the values of the variables i and anInt after each execution of the body of the for loop as this code is executed when the input array arr is [8, 7, 6, 5]. Also write down the value that is returned for this input. (b) To ensure that the code in the given implementation is valid, suggest a precondition that the tivate input arr should satisfy.
