output_description: Print the lexicographically smaller of the two strings. (If the two strings
  are equal, print one of them.)

input_description: Input is given from Standard Input in the following format:
  
      
      
      a b
attempt: x, y = map(int, input().split())
  a = []
  a1 = ""
  a2 = ""
  for i in range(x):
      a1 += str(y)
  a.append(a1)
  for i in range(y):
      a2 += str(x)
  a.append(a2)
  a = sorted(a)
  print(a[0])
  
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?
