Total time limit:

1000ms

Memory Limit:

Describe

The number of non-negative integers of two not exceeding 200 bits is obtained.

Input

There are two lines, each of which is a non-negative integer that does not exceed 200 bits, and may have extra leading 0.

Output

A row, which is the result after the addition. The result can not have redundant leading 0, that is, if the result is 342, then you cannot output to 0342.

Sample input

2222222222222222222233333333333333333333

Sample output

55555555555555555555
