Describe and analyze a data structure to support the following operations on an array a[1 . . n] as quickly as possible. initially, a[i] = 0 for all i. • settoone(i) given an index i such that a[i] = 0, set a[i] to 1. • getvalue(i) given an index i, return a[i] • getclosestrightzero(i) given an index i, return the smallest index j ≥ i such that a[j] = 0, or report that no such index exists. the first two operations should run in worst-case constant time, and the amortized cost of the third operation should be as small as possible. 3

Agas contained within a piston-cylinder assembly e end nation about same energy states, 1 and 2, where pi 10 bar, v undergoes two processes, a and b, between the sam 0.1 m3, ui-400 kj and p2 1 bar, v2 1.0 m2, u2 200 kj: process a: process from 1 to 2 during which the pressure- volume relation is pv constant process b: constant-volume process from state 1 to a pressure of 2 bar, followed by a linear pressure-volume process to +20 0 state 2 kinetic and potential energy effects can be ignored. for each of the processes a and b, (a) sketch the process on p-v coordinates, (b) evaluate the work, in kj, and (c) evaluate process the heat transfer, in kj

Abrayton cycle operates with a regenerator on the air-standard with properties evaluated at 400 k. the tem- perature of the air entering the compressor is 350k while the temperature of the air exiting the compressor is 600 k. the temperature of the air entering the turbine is 1600 k. the overall cycle produced 600 kj/kg of net work out. assuming a regenerator effectiveness of 0.8, what is the temperature of the air before heat addition (combustion)? draw this process on a t - s diagram
