How can you compress a string efficiently to reduce its size while maintaining its original content?

One way to efficiently compress a string while preserving its content is by using algorithms like Huffman coding or Lempel-Ziv-Welch (LZW) compression. These algorithms analyze the frequency of characters in the string and assign shorter codes to more common characters, reducing the overall size of the string. This compression technique is commonly used in file compression programs like ZIP or gzip.
