用火柴棒摆出来的0到9的数字，可按如下规则进行变化：

1.数字移动一根火柴棒可变成其它0到9之间合法的数字

2.数字添加一根火柴棒可变成其它0到9之间合法的数字

3.数字去掉一根火柴棒可变成其它0到9之间合法的数字

现在给出一个带有两个操作数的+,-,*,/的算术式子，需要你判断该式子是否

成立，如给出式子9-6=3，这个符合正常结果，正确；如给出式子

9-6=2，其判断规则如下：

1.变换左操作数可以使式子成立的话，打印出来变化后的算术等式

2.变换右操作数可以使式子成立的话，打印出来变化后的算术等式

3.变化左右操作数可以使式子成立的话，打印出来变化后的算术等式

4.以上变化都无法让等式成立，打印等式无法成立

Put out with a match stick figures of 0-9, according to the following rules changes:

1. Digital Mobile matchstick can become a legitimate number between 0 and 9 other

2. Add a matchstick figure can become legal digital among other 0-9

3. To remove a matchstick figure can become legal digital among other 0-9

Will now be given a two operands with the+,-,*,/arithmetic formula, you need to determine whether the formula

Establishment, as given expression 9-6 = 3, this results in line with the normal and correct　as given formula

9-6 = 2, the judge rules are as follows:

1. Transform the left operand can make equation holds, then print out the mathematical equation after change

2. The right operand can make the conversion formula established, print out the arithmetic equation after change

3. Change the left and right operands can make the formula holds, print out the arithmetic equation after change

4. The above changes can not allow the establishment of equality, equality can not
