4. Assume b is a variable of size 4 bytes and is stored in a byte addressable memory at address DanD. If the processor's endianness is little-endian, and the processor writes the value Uxa 155f0d3 in the variable b, which bytes will be written to each memory address. 5. Assume x is a variable of type pointer that points to a single byte. Further, assume b is a variable of size 4 bytes and is stored at memory address UxaB. Given that the processor uses big-endian, evaluate the new value of b after the following code is executed: b = OXEFSSZ; x = Oanl; b = b+*x
