Knuth-Morris-Pratt linear-time string search: - kmp_table builds failure function in O(|pattern|) - kmp_search scans text once in O(|text|), counting matches - After a hit, k := t.(n-1) so overlapping matches still count kmp_search "abababcabababcababcc" "abab" = 5 Hits at positions 0, 2, 7, 9, 14 (overlapping at 0/2 and 7/9). Tests: nested while-inside-for, char inequality (.<>), pat.[i] string indexing, Array.make 0, combined string + array indexing. 140 baseline programs total.
