Operations on strings<br />
◮ given a string x, a substring of x is any string formed from<br />
contiguous occurrences of symbols in x taken in the same<br />
order in which they occur in x<br />
◮ formally, y is a substring of x iff there exists strings z <strong>and</strong> w<br />
such that x = z ⌢ y ⌢ w<br />
◮ notice that both z <strong>and</strong> w may be empty<br />
