With this provided C program code, how can I convert this to LC$3$ assembly language? With implementation of the functions using subroutines and a properly organized runtime stack.

When your program reaches the HALT instruction in main, you should have the correct output stored in the stack.

If the array $$ar$$ contains the elements: $\{2,3,5,0,1\}$ then the SUMOFSQUARES subroutine should return:

$22+32+52+02+12=4+9+25+0+1=39$

You must use a subroutine called $$SQUARE$$ to calculate the square of each element in the array, so given an input of $5$ the square subroutine should return: $25$

The output of $$SQUARE$$ is then returned to $$SUMOFSQUARES$$ where a running total is kept, adding each square after every loop. sum $=4$ on first loop, sum $=13$ on second loop, sum $=38$ on third loop and so on$.$
