Solve the cryptarithm: `4\ x\ A B C= A B ` does not have any solution.

Explanation

`0` is the only unit digit number, which gives the same `0` at the unit digit when multiplied by `4`.
So, the possible value of `B` is `0`.
Similarly, for `A` also, `0` is the only possible digit.
But then `A`,`B` and `C` will all be `0`.
And if `A`, `B` and `C` become `0`, these numbers cannot be of two-digit or three-digit.
Therefore, both will become a one-digit number.
Thus, there is no solution possible.
