For Java users, remember to use BufferedReader and StringTokenizer instead of Scanner because Scanner is too slow. Scanner gave me TLE while BufferedReader is accepted :) |

You can use Karatsuba Multiplication for solving this problem. It will be O(n^1.585). |

whoever trying to solve this problem, don't use boost library in c++, or Biginteger in java or python here. please learn from the questions and your approaches. don't search for any shortcuts. you won't learn anything if you do. |

Multiplication rule is best for c language very helpful when we multiply large numbers in c language just store the result in a large array. |
