This is similar to the last problem, except that the first number on a line is an ID number that identifies an account. The same ID number may appear on any number of lines. Use a Dictionary to accumulate, for each ID, the sum of all the numbers that are on all the lines with that ID number. Call the input file id_data. txt. Write an output file called ID_sums. txt. On each line of the output fille, print an ID number and the sum. Sort the lines by the numerical order of the IDs

Alook-up table used to convert pixel values to output values on a monitor. essentially, all pixels with a value of 190 or above are shown as white (i. e. 255), and all values with a value of 63 or less are shown as black (i. e. 0). in between the pixels are scaled so that a pixel with a value p is converted to a pixel of value 2/127 −+3969). if a pixel has a value of 170 originally, what value will be used to display the pixel on the monitor? if a value of 110 is used to display the pixel on the monitor, what was the original value of the pixel?

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)
