MIPS Assembly Code: Replacing Characters in a String
Added on -2019-09-23
This text appears to be MIPS assembly code for a program that prompts the user to input a string, then processes the string by replacing certain characters with other characters or sequences of characters. For example, if the input string contains a `#` followed by a number `n`, the program replaces this sequence with `n` occurrences of the character `A`. Similar replacements are performed for the characters `%`, `$`, and `&`. The processed string is then outputted.
