AT_abc441_a [ABC441A] Black Square

There is a grid with $ 10^{100} $ rows and $ 10^{100} $ columns. In what follows, the cell at the $ i $ -th row from the top and $ j $ -th column from the left is denoted as cell $ (i,j) $ . In this grid, only the $ 100\times 100 $ region with cell $ (P,Q) $ as the top-left cell is painted black, and all other cells are painted white. Determine whether cell $ (X,Y) $ is painted black.

The input is given from Standard Input in the following format: > $ P $ $ Q $ $ X $ $ Y $

If cell $ (X,Y) $ is painted black, print `Yes`; otherwise, print `No`.

### Sample Explanation 1 The $ 100\times 100 $ region with cell $ (3,3) $ as the top-left cell is painted black. Cell $ (5,10) $ is included in this region, so print `Yes`. ### Sample Explanation 2 The $ 100\times 100 $ region with cell $ (5,5) $ as the top-left cell is painted black. Cell $ (10,1000) $ is not included in this region, so print `No`. ### Sample Explanation 3 The $ 100\times 100 $ region with cell $ (1,2) $ as the top-left cell is painted black. Cell $ (1,1) $ is not included in this region, so print `No`. ### Constraints - $ 1 \leq P,Q,X,Y \leq 10000 $ - $ P,Q,X,Y $ are integers.
