Move the match stick to determine if the equation is valid

1: Read a formula from the keyboard (the formula is definitely a non-tenable equation).
2: Judge whether a stick can be moved to make the equation, then output a new equation, otherwise output No.

A The number in the formula can only be positive, the operation symbol will only appear plus and minus signs, and there is only one equal sign, no parentheses, multiplication sign or division sign, no + +,--, + + or-+ appear.
b The equation can only be integers and less than 10
C You can't move the stick, so the plus, minus, and equal signs don't change. Before and after the move, the number of sticks must be exactly the same as that shown in the computer.
D The number of the formulas that are read from the keyboard does not start with 0, but allows the numbers in the modified equation to begin with a number.
