Must work on Big Endian 7. Thanks!!

Draw a detailed flowchart and write an ARM assembly program to determine whether a string of printable ASCII letters (from a to z or from A to Z, case insensitive) stored in memory is a palindrome (i.e., the letters in the string are the same from left to right as from right to left, case insensitive) or not. If palindrome, you should store 1 in r0. if not, you store 2 in r0 Your code should be highly optimized. Use as few instructions as possible (as little as 21 assembly instructions only)!! gnore all characters that are not letters. You should also treat capital and small letters the same, i.e., case insensitive. For example, "madam", "deleveled", "Noon", "He lived as a devil, eh?", and "Was it a car or a cat I saw?" are palindrome strings. However, "madam, I am Adam." is not a palindrome string. A string can have even or odd number of characters and must end with character 0x00 (i.e., the ASCII code of the null character) Define in your assembly program the string as follow: STRING DCB "He lived as a devil, eh?" string EoS end of string DCB 0x00
