You are given three positive integers $ A $ , $ B $ , and $ C $ . Print `Yes` if $ A $ , $ B $ , and $ C $ are all equal, and `No` otherwise.

The input is given from Standard Input in the following format: > $ A $ $ B $ $ C $

Print `Yes` if $ A $ , $ B $ , and $ C $ are all equal, and `No` otherwise.

### Sample Explanation 1 $ A=B=C=3 $ , so $ A $ , $ B $ , and $ C $ are all equal. Thus, `Yes` should be printed. ### Sample Explanation 2 $ A=7 $ and $ C=8 $ , so $ A $ and $ C $ are not equal. Thus, `No` should be printed. ### Constraints - $ 1\leq A ,B,C\leq 9 $ - $ A $ , $ B $ , and $ C $ are integers.
