Understanding Recursion in FindSequence Function
The provided findSequence function operates on the principle of brute force search with backtracking. Here's a step-by-step explanation of its recursive nature:
At each recursive call, the function attempts two possible transformations:
The recursive calls continue, starting from 1 and exploring these additions and multiplications until one of the following conditions is met:
Example: Reaching the Goal of 14
To illustrate the working of the recursion, let's trace the steps taken to find a sequence for the target 14:
This detailed explanation provides a clear understanding of the recursion process in the findSequence function, allowing the reader to appreciate its search strategy and the role of backtracking in finding a valid sequence for the given goal.
