Please do these in RISC-V not C

The following assembly programs have to be implemented in RISC - V simulator. Accept a string of length n from the user. The string should have an arbitrary number of zeros spread over it for example: "000compOu000teor" or "cOmOoputer00" etc. Write a program in assembly to extract all the zeros from the string and the print it on the console without any zeros. Also output the number of zeros extracted. Maximum file size: 100MB, maximum number of files: 1
