An array of prime numbers 2-499 is stored in a file "primeNumbers.txt". This program can allow to request a number from the user and find the closest prime number to the input number (either higher or lower) and print the lower one if the number is in the middle of two. Your program should run interactively until the user quits. Try to minimize the program execution time by using the appropriate searching method for finding the prime number(s). You need to record and report the number of comparisons executed for finding the prime numbers. Sample Output Enter a number between 2 and 499.1 This number is outside the accepted range.
