Assume a byte-addressable memory is organized as a 32-bit word. There is a program in the RAM which needs to read string as a user input. Assume each of these characters are read in ASCII form and stored in the successive memory location starting from address 4000. If the user enters the string Checkbox, then show how this string is stored in the memory which uses: a. Big-Endian Scheme b. Little-Endian Scheme
