Subject: [PATCH] Clarified instructions for Pairwise algorithm (#17013)

* Clarified instructions for Pairwise algorithm

Added an example to further clarify the directions in the "Pairwise" algorithm, per issue #16800 https://github.com/freeCodeCamp/freeCodeCamp/issues/16800

* Change "for example" to "for instance"
