Design, implement, and execute a C-program that does the following: It allocates memory for a sequence of 3m arrays size 800,000 elements each; then it explicitly deallocates all even-numbered arrays and allocates a sequence of m arrays of size 900,000 elements each. Measure the amounts of time your program requires for the allocation of the first sequence and for the second sequence. Choose m to exhaust almost all of main memory available to your program. Explain your time
