Chris recently received an array p as his birthday gift from Joseph, whose elements are either 0 or 1. He wants to use it to generate an infinite long superarray. Here is his strategy: each time, he inverts his array by bits, changing all 0 to 1 and all 1 to 0 to get another array, then concatenate the original array and the inverted array together. For example, if the original array is [0,1,1,0] then the inverted array will be [1,0,0,1] and the new array will be [0,1,1,0,1,0,0,1]. He wonders what the array will look like after he repeat this many many times. He ask you to help him sort this out. Given the original array pp of length n and two indices a, b (≪≪, means much less than) Design an algorithm to calculate the sum of elements between a and b of the generated infinite array p^, specifically, ∑≤≤p^. He also wants you to do it real fast, so make sure your algorithm runs less than O(b) time. Explain your algorithm and analyze its complexity.

You need to design a circuit that implements the functions in the following table: s0 s1 function0 0 a + 10 1 a – b1 0 a + b1 1 a – 1s0 and s1 are 1-bit control inputs to select the function of the circuit. inputs a and b are 4-bitnumbers in 2s complement form. the output is also a 4-bit number in 2s complement form.you are allowed to use only one ttl 7483 4-bit adder to implement all the functions. but anynumber of other components (except the adder) can be used.hint: design a combinational logic circuit to modify the input b and the “carry input” of theadder depending on the control inputs s0 and s1.important: lab grade will depend on the working of the circuit & will be checked of by your labinstructor.1. is the output valid for the following input combinations: a. s0 = 0, s1 = 0, a = 7, b = 3? b. s0 = 0, s1 = 1, a = 7, b = 3? c. s0 = 1, s1 = 0, a = -4, b = -5? d. s0 = 1, s1 = 1, a = -8, b = 6? 2. what is the range of inputs (for both a and b) that will produce the valid output for all the functions?

These statements describe lists in presentation programs: a. bullets can be turned off and on. b. bullets cannot be turned off. c. bullet styles, colors, and sizes can be changed. d. lists don't have to use bullets or numbers. e. numbering styles, colors, and sizes can be changed. f. numbers can be turned off and on. g. numbers cannot be turned off. select all that apply
