Identifying the pattern generation pattern

The pattern generation technique can only be used to solve some specific problems. These are generally easy or medium problems involving arrays or strings, where we must assign a unique pattern value to the input sequence. In most cases, applying the pattern generation technique does not solve the problem; it only generates a pattern string. This pattern string is then used along with other problem contexts to partially or completely solve the problem.

If the problem statement or its solution follows the generic template below, it can be solved by applying the counting technique.
