Part 2 (12 marks): Implement the procedure atoi in assembly MIPS, which does conversion (casting) of a null-terminated ASCII string to integer. This procedure takes as argument into register Sa 0 one pointer to the first character of the string and returns the value of the corresponding integer in register SvO. The string must contain only combinations of digits 0-9. If any other character appears, then the procedures interrupts its execution by returning to register Sv0 the value -1. For example, if Sa0 points to memory a sequence of bytes with values 50 S21 010, then the procedure must return to Sv0 the value: 24 SOLUTION
