A checksum is a single number that can act as a kind of "digital signature" of a long string. Just like how two people will have different handwritten signatures, two strings can have two different digital signatures. There are many ways to calculate the checksum of any arbitrary string; the more complex the calculation, the less likely it is for two strings to have the same checksum value. Write a program that prompts for a string of characters and outputs the checksum. Use any of the lines in the attached file "SolarFuels.txt" as the string of characters for the checksum. The checksum for this program should simply be the sum of the ord() values of each character, modulo 10. For example, the checksum for the string "cat" would be (99 + 97 + 116) % 10 which is 2 1. 2. Write a program that can report the number of times the word "the" appears in a file attached file "SolarFuels.txt". Prompt the user for the filename and the word to search for and display the number of times the word "the" appears in the file
