Knuth-Morris-Pratt algorithm

Tired of the meaningless $ABC$ strings in the theory? Let's see if you can come up with cooler ones.

Your task is to think of a pattern $s$ and a string $t$, such that the KMP algorithm finds the presence of $s$ in $t$ exactly after $5$ shifts. Write each string on a new line.

Answer example:
