Aprogram is written that reads a list of numbers from afile, writing them into a vector ofints. assume that the filecontains n numbers. the program thencomputes the average of the numbers, using thevector. it then sorts the numbers, using a bubble sortalgorithm. finally, it prints the average and thesorted list to a second file.
(a) which operations are done just once in thisalgorithm?
(b) which operations are repeated ntimes?
(c) which operations are repeated n2 times?
(d) what is the asymptotic complexity ofthis program's algorithm? express your answer in big-onotation.
