diff template library written in C++
dtl is a C++ template library which provides functions for comparing two sequences of arbitrary types. The sequences to be compared must support a random-access iterator.
The algorithm dtl uses is based on the paper "An O(NP) Sequence Comparison Algorithm" (1989) by Sun Wu, Udi Manber and Gene Myers. The computational complexity of Wu's Algorithm is O(N+PD) on average, and O(NP) in the worst case.
