## Gapped Genome Path String Problem

Reconstruct a string from a sequence of (k,d)-mers corresponding to a path in a paired de Bruijn graph.

Given: A sequence of (k, d)-mers (a1|b1), ... , (an|bn) such that Suffix(ai|bi) = Prefix(ai+1|bi+1) for all i from 1 to n-1.

Return: A string Text where the i-th k-mer in Text is equal to Suffix(ai|bi) for all i from 1 to n, if such a string exists.
