Question: The string reversal operator sR reverses the string. For example, (0100011) R = 1100010, and (bravo) R = ovarb. The language reversal operator is defined

The string reversal operator sR reverses the string. For example, (0100011) R = 1100010, and (bravo) R = ovarb. The language reversal operator is defined as follows: LR = {WR WE L} Show that regular languages are closed under reversal. (Hint: Show how to transform a regular expression to express the reversal of the language.)
