In simple word loop variant is some predict or condition that holds the every iteration of the loop.
here, In while loop condition is (i < len)
so, (i < len ) is loop varient

Write a PYTHON program that allows the user to navigate the lines of text in a file. The program should prompt the user for a filename and input the lines of text into a list. The program then enters a loop in which it prints the number of lines in the file and prompts the user for a line number. Actual line numbers range from 1 to the number of lines in the file. If the input is 0, the...

answer. A4 Consider a formal argument which has two premises: “p implies not q”, and “p or not q”, with the conclusion that “q is false”. a. Is this a valid argument? Give a truth table that verifies your b. Convert the statement “any integer less than C is also less than Cz" into “r implies s” form: i.e. what are the statements r and s?
