Write a method called ispalindrome that accepts a queue of integers asa parameter and returns true if the numbers in the queue are the same inreverse order. for example, if the queue stores [3, 8, 17, 9, 17, 8,3], your method should return true because this sequence is the same inreverse order. if the queue stores [3, 17, 9, 4, 17, 3], your methodwould return false because this sequence is not the same in reverseorder (the 9 and 4 in the middle don't match). the empty queue shouldbe considered a palindrome. your method must restore the parameterqueue to its original state before returning. use one stack as auxiliarystorage.

Consider a power plant with water as the working fluid that operates on an ideal rankine cycle. it has a net power output of 45mw. superheated steam enters the turbine at 7mpa and 500°c (h=3411.4 kj/kg; s=6.8 kj/kg k) and is cooled in the condenser at a pressure of 10 kpa by running cooling water from a lake through the tubes of the condenser at a rate of 2000 kg/s. (a) show the cycle on a t-s diagram (a right schematic is fine - you do not need to calculate the temperatures at each point); (b)-determine the work done by the turbine and the pump in kj/kg; (c)-the mass flow rate of water used by the power plant; (d)-the thermal efficiency of the cycle; (e)-the temperature rise of the cooling water. assume the cooling water is incompressible with cp 4.18 kj/kg°c.
