Consider an iterative series 1, (-1)/2, 1/3, (-1)/4, 1/5,…(-1)^(k-1)/k. The first 5 terms for k=1:5 are written here. Create the first 100 and store them all in a preallocated array A using a for loop.
Please help with this question. Thanks in advance!

https://in.mathworks.com/help/matlab/matlab_prog/preallocating-arrays.html - you will see how to store values in each iteration through preallocation.

One last thing, what are the tic toc functions doing then? I've only learned about for and while loops. And, I was curious how this function works without incorporating either. Thank you so much for the help.
