Question

use C Program Recamán's Sequence

Implement this in a program. Write two functions, one for solving it iteratively, one for solving it recursively.

Take two arguments from the command-line: an "i" or "r", and the term number (how many terms to print).

Print out which method executed (was selected) and all the terms (and the number of terms

Expert Solution
Step 1

The provided code generates Recaman's Sequence, an integer sequence where each term is defined as the previous term minus the index, unless the result is negative or has already been used, in which case it is defined as the previous term plus the index. The code implements two methods for generating the sequence: an iterative function and a recursive function.

The user must provide two arguments from the command line: either "i" or "r" to indicate which method to use, and a term number (an integer) to indicate how many terms of the sequence to generate. The code then either uses the iterative function or the recursive function to generate the requested number of terms, and prints the terms and the number of terms generated.
