Write a function which, for a word size $(8-$dgit hexadecimal$)$ number passed in r $2,$ separates and stores each digit of the hex number in a memory the starting address of which is passed in r $3,$ highest digit in the lowest address.

Write a function which, for a given decimal number $(0-9)$ passed in r $2,$ generates and returns in r $0$ a number whose bit pattern with $\text{'}1\text{'}$s forms a bar $($made by $\text{'}1\text{'})$ chart$-$like shape with the count of bars the same as the decimal number. Example is provided below.

Use the lookup table approach.

Input r$2$ Output r$0[$in binary representation$]$

$10$x$000000010$b$00000000000000000000000000000001$

$30$x$000000070$b$00000000000000000000000000000111$

$70$x$0000007$F $0$b$00000000000000000000000001111111$

$3.$ Write a complete code which displays a bar chart $($as explained in $2$ above$)$ for each digit of your Howard ID $(003032412),$ calling above $2$ functions and, in order to see the changes in the LED pattern, the $1$ sec $-$delay function.

NUMBER $2$ HAS AN EXAMPLE USE THE LOOKUP TABLE APPTOACH

$($i$)$ write a code for number $3$ which includes number $1$ and number $2$ as funtions in it$.$

$($ii$)$ add comments which sufficiently explain your coding design, allocatiob of registar to variables, etc.
