QUESTION 1 (50 marks) A string is an array representing a sequence of characters. To store a string of n characters in your program, you need to set aside n+1 bytes of memory. This allocated memory will contain the characters in the string, plus one extra special characterthe null characterto mark the end of the string. The null character is a byte whose bits are all zeros (0x00). The actual string consists of any group of characters, which none of them can be the null character. Draw a detailed flowchart and write an ARM assembly language program to copy a null terminated STRING1 to a null terminated STRING2, after removing any occurrences of the word the in STRING1. I.e., if STRING1 is the woman and The man said the then STRING2 would become woman and The man said . However, if STRING1 is and they took breathe then STRING2 would become and they took breathe without any change. You can assume that STRING2 will be less than 255 characters. Your code should be highly optimized. Use as few instructions as possible (as little as 30 assembly instructions only, NOT including assembly directives or data definitions)!!. Define the data of this program in a separate DATA area. Define the strings as follow: STRING1 DCB "and the man said they must go" EoS DCB 0x00 STRING2 space 0xFF ;String1 ;end of string1 ;just allocating 255 bytes More test cases: "the the the 123 """" "the" "" the"" 123 " "The" "The" "them the the1" "them the1"
