Gateforum Test Series: Algorithms - Dynamic Programming
Given a text array $T[1…..n]$ and a pattern array $P[1….m]$ such that T and P are character taken from alphabet $\sum$, $\sum={a,b,c,…..z}$. String matching problem is to find all the occurence of P in T. A pattern occur with shift s in T if $P[1…..m]=T[s+1,…...s+m]$. Consider $T=bacacbaacacac$ $P=cac$ The sum of the value of all s is ________
