We have $10$ integer numbers in the num array $($of word type, each element is $16$ bit$).$ Write an assembly code to evaluate the following expression: $Ax=$

$um[0]+$

$um[1]+$

$um[2]+$dots$+$

$um[9].$

We have three integer numbers in the num array $($of byte type, each element is $8$ bit$).$ Write an assembly code to evaluate the following expression: $Bx={100}^{**}$ num $[0]+{10}^{**}$ num $[1]+$ num $2.$

We have a character array str of length $20.$ Write an assembly code which assigns the index of the first appearance of the character $\text{'}d\text{'}$ in the string to the register BX$.$ If the character $\text{'}d\text{'}$ is not found in the string str$,-1$ is assigned to the register $Bx.$
