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()
n = len(s)

for i in range((n-1)**2):
  tmp = int(s[0])
  for j in range(0, n-1):

    if (i>>j)&1:

    else:
      tmp -= int(s[j+1])

  if tmp == 7:
    ops = i
    break

res = ""
for i in range(n):
  res += s[i]
  if i < n:
    if (ops>>i)&1:

    else:
