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.
A, B, C, D=list(map(int, list(input())))

for b in [B, -B]:
  for c in [C, -C]:
    for d in [D, -D]:
      if A+b+c+d==7:
        output=str(A)
        
        if b<0:
          output+=str(b)
        else:
          output+='+'+str(b)
          
        if c<0:
          output+=str(c)
        else:
          output+='+'+str(c)
          
        if d<0:
          output+=str(d)
        else:
