3. The file system in an OS needs to keep track of disk blocks that are in use (i. e., part of a file) and those that are not in use (i. e., not yet used in a file, or formerly part of a file now deleted). One way to do this is with a bitmap in which each disk block is represented by 1 bit indicating the block’s status (free or busy). For a filesystem with 1,464,145,922 512-byte blocks, how many 512-byte blocks would be needed to hold the bitmap

Least square fit to polynomial write a function leastsquarefit3pol that solves a linear system of equations to find a least squares fit of a third order polynomial to an experimental data set given as two row arrays. the function leastsquarefit3pol must explicitly solve a set of linear equations and cannot use polyfit. there should be no restriction on the size of the problem that can be solved.
