Question

Write an LC-3 program (starting at memory location 0x3000) to take a string as input and then output information about this string. The end of the string will be denoted with the "#" character. Once the "#" has been found, output the following in order:
1) The letter “u” followed by the number of uppercase letters in the string (A-Z)

2) The letter “l” followed by the number of lowercase letters in the string (a-z)
3) The letter “n” followed by the number of numbers in the string (0-9)
4) The letter “o” followed by the number of characters that do not fit in any of the categories above (ex: $%@!)

Note that the "#" character should not be included in the count of the last category. Your entire output should be on a single line . All letters should be lowercase .

You may assume that there will be between 0-9 characters in each category (i.e. you do not have to handle multiple digit output).

Sample input:

a4FR!!bc?#

Sample output:

u2l3n1o3
