Q3: Write a complete C++ program that contains the integer functions (main, funx and funy). The main function declares an integer (k), which is assigned a value using cin. Then print funx(k), where funx(n)=2*funy(n-1) if n >1 and funx(n)=1 if n<=1. And funy(n)=3*funx(n-1)-1 if n>1 and funy(n)=1 if n<=1. *
