2.37 [5] Write a program in MIPS assembly language to convert an ASCII number string containing positive and negative integerdecimal strings, to an integer. Your program should expect register $a0 to hold the address of a nullterminated string containing somecombination of the digits 0 through 9. Your program should compute the integer value equivalent to this string of digits, then placethe number in register $v0. If a non-digit character appears anywhere in the string, your program should stop with the value −1 inregister $v0. For example, if register $a0 points to a sequence of three bytes 50ten, 52ten, 0ten (the nullterminated string “24”),then when the program stops, register $v0 should contain the value 24ten.
