Write a function with declaration void minusoddcolumn(int** mat, int n) where n ≥ 1 and mat is an n × n 2d-array of non-negative integers. the function should find the column in mat with more odd numbers and replace all of its elements with -1. if multiple columns have the highest presence of odd numbers, the first of them (i. e. the one with the lowest index) should be chosen to have its elements replaced by -1

Air inially occupying a volume of 1 m2 at 100 kpa, 27 c undergoes three internally reversible processes in series. process 1-2 compression to 500 kpa during which pv constant process 2-3 adiabatic expanslon to 100 kpa process 3-1: constant-pressure expansion to 100 kpa (a) calculate the change of entropy for each of the three processes. (b) calculate the heat and work involved in each process. (c) is this cycle a power cycle or refrigeration cycle?
