Afile uses 10 direct blocks, a completely full indirect block and one double-indirect block. the latter has just one entry to a half-full indirect block. how many disk blocks does the file use, including its content, and all indirect, double-indirect blocks, but not the inode itself? a sketch would be useful.

Design a pos circuit that displays the letters a through j on a seven-segment indicator. the circuit has four inputs w, x, y, and z which represent the last 4 bits of the uppercase ascii code for the letter to be displayed. thus, if wxyz = 0001 then "a" will be displayed. (any answer with 22 or fewer gates and inverters, not counting any for the inputs, is acceptable)

Given int variables k and total that have already been declared, use a while loop to compute the sum of the squares of the first 50 counting numbers, and store this value in total. thus your code should put 11 + 22 + 33 + + 4949 + 50*50 into total. use no variables other than k and total.
