Use MARS to write and simulate a MIPS assembly language program to implement the strLen function. Write the main function to call strLen.

The main function should: Pass a string to strLen using registers $a0.

Preserve (i.e. push onto the stack) any T registers that the main function uses. The strLen function should:

Preserve any S registers it uses.

Determine the length of the string.

Return the length of the string to main using register $v0.

Note: A string is passed to a function by passing the starting address of the string.

Note: A C-style string is a null-terminated character array
