Given that the ASCII codes for 'A' through 'Z' are x41 through x5A; and the codes for 'a' through 'z' are x61 through x7A: What are the bit-mask and the logic operation (as well as the LC3 instruction) that would force a character stored in R0 to upper case - i. e. convert a lower case character stored in R0 into upper case, and leave an upper case unchanged (so ‘a’ would become ‘A’, and ‘A’ would remain ‘A’).
