codesignal 1-3 문제풀이

1. Write a function that returns the sum of two numbers.

• Example)
  -> For param1 = 1 and param2 = 2, the output should be add(param1, param2) = 3.

def add(param1, param2):
    return param1 + param2

2. Given a year, return the century it is in.The first century spans from the year 1 up to and including the year 100, the second - from the year 101 up to and including the year 200, etc.

• Example)
  -> For year = 1905, the output should be centuryFromYear(year) = 20
  -> For year = 1700, the output should be centuryFromYear(year) = 17

def centuryFromYear(year):
    return (year-1) // 100 + 1

3. Given the string, check if it is a palindrome.

• Example)
  -> For inputString = "aabaa", the output should be checkPalindrome(inputString) = true.
  -> For inputString = "abac", the output should be checkPalindrome(inputString) = false.
  -> For inputString = "a", the output should be checkPalindrome(inputString) = true.

def checkPalindrome(inputString):         
    return inputString == inputString[::-1]
