It is stated in this chapter that when nonlocal variables are accessed in a dynamic-scoped language using the dynamic chain, variable names must be stored in the activation records with the values. If this were actually done, every nonlocal access would require a sequence of costly string comparisons on names. Design an alternative to these string comparisons that would be faster.

See the explanation for the answer.

Explanation:

As in the dynamically scoped language, using the dynamic chain, variable name must be stored in the activation records with the values. The alternative strategy is as follows:

Collection sort() can be used for this as an alternative to compare the String which is completely based on a different way by implementing interfaces for comparison and sorting being happened in different ways.
