You are given 9 runs that have 50, 100, 250, 300, 350, 400, 450, 500 , 600 equal- length records. it takes 10 seconds to read and 20 seconds to write one block from/to disk. it takes 10 seconds of cpu time to merge one block of records. assume that all input, output, and cpu processing is sequential (i. e. input, output, and cpu processing is not overlapped or done in parallel). the block size is 50 records. (a) give an optimal 4-way merging scheme to merge the 9 runs into 1. (b) what is the total time taken by the optimal scheme?
