Sitting in a station waiting room, Joisino is gazing at her train ticket.  The ticket is numbered with four digits A, B, C and D in this order, each between 0 and 9 (inclusive).  In the formula A op1 B op2 C op3 D = 7, replace each of the symbols op1, op2 and op3 with `+` or `-` so that the formula holds.  The given input guarantees that there is a solution. If there are multiple solutions, any of them will be accepted.
s = input()

for i in range(2**(n-1)):

  #print(b)
  for j in range(n):
    f += s[j]
    if b[j] == '0':
      f += '-'
    else:
      f += '+'
  f = f[:len(f)-1]
  if eval(f) == 7:
    print(f)
