$11\mathrm{.}4$ LAB: Array of squares $-$ LDUR$/$STUR

Given an array of four integers, write a program that populates a new array with the square of the elements in the given array. Assume X$19$

stores the memory location of the first element of the given array, and X$20$ stores the memory location of the first element of the new array.

Hint: Each memory address is incremented by $8$ due to the doubleword addresses.

Ex: If X$19$ and X$20$ are initialized in the simulator as $4000$ and $5000,$ and the content of the given array is:

then the content of the new array is: stores the memory location of the first element of the given array, and X$20$ stores the memory location of the first element of the new array.

then the content of the new array is:

Note: Use the $\text{'}+\text{'}$ button under the Registers and Memory display to initialize X$19,$ X$20,$ and the four memory locations of the given array. Note: Use the $\text{'}+\text{'}$ button under the Registers and Memory display to initialize X$19,$ X$20,$ and the four memory locations of the given array.
