Problem Using recursion, write a program in C++ implementing a function with one positive int parameter called n. The function will write 2-1 integers. Here are the patterns of output for various values of n: n-1: Output is: 1 n=2: Output is: 1 2 1 n=3: Output is: 1 2 1 3 1 2 1 n-4: Output is: 1 21312141213121 And so on. Note that the output for n always consists of the output for n-1, followed by n itself, followed by a second copy of the output for n-1. Deliverables
