(b) A map-reduce operation produces from input data (1,5,10,2) the output 130, and for the input data (1,10,20) it outputs 501. Write down a possible map-reduce program that would produce this output, and write down the steps for computing the output of this program on the following input values: 1,3,4,6,11,12.
