Let e=2.718 be the base of the natural logarithm. Create three arrays A,B,C each of which is a row vector with 107 entries such that A(k)=B(k)=C(k)=e1/kcos(k2+3) for 1k107, as follows: - The array A is created using a for loop without a pre-initialization of the array. - The array B is created using a for loop and it is first pre-initialized using the zeros command. - The array C is created without using a loop. For each of the three arrays use the functions tic and toc to measure the time needed to create it (this includes the pre-initialization for array B ). Determine which method is most efficient, and which method is least efficient
