input_description: Input is given from Standard Input in the following format:
  
      
      
      a b
attempt: a,b=map(str,input().split())
  res = ""
  if a < b:
    for i in range(b):
      res += a
  else:
    for i in range(a):
    res += b
  print(res)
problem_description: Statement
  
  Given are 1-digit positive integers a and b. Consider these two strings: the
  concatenation of b copies of the digit a, and the concatenation of a copies of
  the digit b. Which of these is lexicographically smaller?
