in java 23.19(Calculating the Sum of the Squares) Section 17.7.3 used map and sum to calculate the sum of the squares of an IntStreams values. Reimplement stream pipeline in Fig. 17.9 to replace map and sum with the following reduce, which receives a lambda that does not represent an associative operation:
.reduce((x, y)-> x + y * y)
Error-Prevention Tip 17.2 cautioned you that reduces argument must be an associative operation. Execute the reimplemented stream pipeline using a parallel stream. Does it produce the correct sum of the squares of the IntStreams values?
