WebOct 8, 2024 · The KMP algorithm pre-computes pat [] and creates an array lps [] of size m (same as the size of pattern) which is used to jump characters while matching. We search for lps in sub-patterns. More commonly we focus on sub-strings of patterns that are either prefixes and suffixes.

So, we will compute new interval bt comparing S [0] to S [i] i.e. string starting from index 0 i.e. from start with substring starting from index i. And find z [i] using z [i] = R - L + 1. Step 2: Else if, i ≤ R, [L, R] can be extended to i. For k = i-L, z [i] ≥ min (Z [k], R-i+1).
