What does the Repeat function achieve in string manipulation?

The Repeat function is specifically designed to create a new string by repeating the specified input string a defined number of times. For instance, if the input string is "abc" and the repeat count is 3, the function will produce "abcabcabc". This capability is particularly useful in various scenarios such as formatting output, creating patterns, or filling up space with repeated characters.

The other functions mentioned do not align with the primary purpose of the Repeat function. Replacing text pertains to modifying existing content, extracting substrings relates to obtaining a segment of the original string, and capitalizing the string affects the case of the characters rather than repeating them. Thus, the Repeat function is distinguished by its straightforward utility in generating multiple instances of a string.
