Display the total count of letters, digits, special characters, and lines. look at the sample.. assume you have the txt file.. put comments for understanding

Counting Letters, Digits, Special Characters and Lines in a Text File Write and test a MIPS assembly language program to count each letter, digit, special character, and number of lines in a text file. The program should do the following: a) Open a text file "input.txt" and read all characters into an array in memory. Limit the length of the array to 10000 characters. The maximum number of characters to be read should be 10000 characters. The actual number of characters depends on the file length. MARS provides the system calls for opening and reading a text file. If the file does not exist then the program should display an error message and terminates. b) Traverse the array character by character. Count all letters, digits, and all other special characters. In addition, count the lines (A line ends with a ' ' character). A single-letter/word line is also counted. Do not distinguish between capital and lowercase letter. c) Display the total count of letters, digits, special characters, and lines. If file "input.txt" does not exist in the same folder then output the following error message: Error: input.txt does NOT exist. If file "input.txt" exists then output the following after counting all letters, digits, etc. Letters = 126 Digits = 27 Special Characters = 35 Lines = 31
