Assume that register $10 and $11 contain a 64-bit unsigned integer with the high part (i.e., the most significant 32 bits) in $10 and the low 32 bits in $11. Similarly a second 64-bit unsigned integer is contained in registers $14 (high 32 bits) and $15 (low 32 bits). Write down a sequence of MIPS true-op instructions that, without causing an overflow exception, would subtract the 64-bit integer in $14 and $15 from the 64-bit integer in $10 and $11 and place the 64-bit difference into registers $8 and $9.
