Write a complete MIPS program that counts the number of l$\text{'}$s in "Hello World!

$".$

Write a MIPS loop that converts a string to lower case.

The address of the string exists in register $$a0.$

$-$The string is terminated with a null character.

The string should be read, converted, and stored in memory.

Check each character if it$,$ is an upper case letter $($range $\text{'}A\text{'}$ to $\text{'}Z\text{'})$ before converting it to lower

case. Recall that $\text{'}A\text{'}=041$ and $\text{'}a\text{'}=061$

Write a complete MIPS program that finds the sum of squares from $1$ to $1$

$1^2+2^2+$cdots$+{10}^2=385$

Output:
