Left-Pad could be the next FizzBuzz. Let's code it in 13 Languages: Javascript, Python, Java, C++, Go, Perl, C#, Haskell, PHP, Ruby, Scala, Scheme & Shell (Bash).

Implementing Left-Pad in 13 Languages

def leftPad(inputStr, paddedLength, ch='.'):
  if len(ch) != 1:
    raise Exception('Invalid Input')
  
  paddedLength = paddedLength - len(inputStr)
  return ch * paddedLength + inputStr 
  
print leftPad('1', 1)
print leftPad('2', 2)
print leftPad('3', 3)
print leftPad('4', 4)
print leftPad('5', 5)
print leftPad('hello', 7)
print leftPad("foo",  6)
print leftPad("foo", 3)
print leftPad("foobar", 3)
print leftPad("foo", 6, "?")
