i want to solve this question with groupbykey or mapReduce in scala spark-shell

Second Question [4 Marks]: Assume that you have the following dataset: {45,3,4,44,39,11,7,8,13,21,20, 44,44,12,27,27,29,18,19,19,1,1,31,31,32,1,22,33,31,37,50,41,42}. Notice that the the lowest value in this dataset is 1 and the largest value is 50 . Assume that you want you to find the average and the count of the values in ranges of 10 s where the ranges are . Write a spark job to solve this problem, then trigger the execution by .collect(Q action and print the returned array. (Hint: refer to example 3, lab 6)
