Explanation / Answer

# Write the following functions. # a. def firstDigit(n) (returning the first digit of the argument) # b. def lastDigit(n) (returning the last digit of the argument) # c. def digits(n) (returning the number of digits of the argument) # For example, firstDigit(1729) is 1, lastDigit(1729) is 9, and digits(1729) is 4. Provide a # program that tests your functions. # FUNCTIONS def digits(n): numDigits = 1 while n >= 10: numDigits += 1 n /= 10 return numDigits def firstDigit(n): numDigits = digits(n) for i in range(numDigits - 1): n /= 10 return int(n) def lastDigit(n): return n % 10 def main(): n = int(input("Enter n: ")) print("First digit:", firstDigit(n)) print("Last digit:", lastDigit(n)) print("Total digits:", digits(n)) # PROGRAM RUN main()
