Find Patterns Forming Clumps in a String solved by 2586

Given integers L and t, a string Pattern forms an (L, t)-clump inside a (larger) string Genome if there is an interval of Genome of length L in which Pattern appears at least t times. For example, $\color{green}{\text{TGCA}}$ forms a (25,3)-clump in the following Genome: $\text{gatcagcataagggtccc}\color{green}\textbf{TGCA}\color{black}\text{A}\color{green}\textbf{TGCA}\color{black}\text{TGACAAGCC}\color{green}\textbf{TGCA}\color{black}\text{gttgttttac}$.
