#### Copy this to a file( name it  f11.asm) and save on  your class account.   
#### Use this file for your solution.  
#### Your entire solution should be on this file.
##
##  Problem  0 : Write down your name and your  account.
##  Your  Name :  #######
##  Your  Account: #######

##  Problem  1(20pts): 

## LOOP:
## 0x400000  add $s2, $s3, $s4
##  addi  $t1, $t2,0x20
##  nop
##  beq  $t2, $t3, LOOP	
##
## (For the problem 1)
## Write  Machine code for the above 4 instructions without looking the Book or Notes.
## (Hexadecimal format)
## Hint:
## opcode for add is 0 and func field is 0x10.
## opcode for addi is 8 and think about rt and rs fields.
## opcode for beq is 4
## register number for $s0 is 16 
## register number for $t0  is 8
## Your solution goes here

##//Problem  2(80pts) 
##Use “ main” at the beginning instead of “__start ” and 
##assume  delayed branch  when you are using xspim or pcspim .
##Write a MIPS program to print the words just like the output format (which is given)  
##after you read the text(textdata) 
##After scanning textdata,you are required to write a program to print 
##a) whole text 
##b)each word one at a time based on the order of each word
##(print all words in ascending order; the example is given at the output format.).
##Words here means character or group of characters separated by space. 
##For the simplicity of the program, assume every character in the paragraph is upper case. 
##Also assume the longest word length is 8 and the number of total words is less than 16.
