- res := res + last character of s.
- if cnt > 1, then. res := res concatenate cnt.

Why do we compress data?
The main advantages of compression are reductions in storage hardware, data transmission time, and communication bandwidth. This can result in significant cost savings. Compressed files require significantly less storage capacity than uncompressed files, meaning a significant decrease in expenses for storage.
