Here is an example of a context-free grammar (CFG) where the number of 'a's and 'b's in a string are the same:

S - aSb bSa SS

In this CFG, 'S' represents a string where the number of 'a's and 'b's are equal. The rules allow for the production of strings with equal numbers of 'a's and 'b's by recursively adding 'a' and 'b' pairs or by combining two strings with equal numbers of 'a's and 'b's. The '' represents an empty string.

What is an algorithm in computer science and can you provide an example to illustrate its function?

An algorithm in computer science is a step-by-step procedure or set of rules used to solve a problem or perform a task. It is a sequence of instructions that can be executed by a computer to achieve a specific goal. For example, a simple algorithm for finding the largest number in a list of numbers would involve comparing each number in the list to the current largest number found so far. The algorithm would update the current largest number if a larger number is found, and continue this process until all numbers in the list have been checked.
