Huawei Test Coordinate movement

Develop a coordinate calculation tool, a means move to the left. D means move to the right. W means move up, s means move down.

Start from (0,0) point and read some coordinates from the input string. The input results are finally output to the output file in the polygon.

Input:

Valid coordinates are a (or D or W or s) + number (within two digits)

to divide between coordinates;

Illegal coordinate points need to be discarded.  such as AA10;  A1A;  $%$; YAD; such as

Here is a simple sample such as:

A10; S20; W10;d30; X A1A; B10A11;; A10;

Processing process:

Starting point (0,0)

+ A10 = ( -10,0)

+ S20 = ( -10,-20)

+ W10 = ( -10,-10)

+ D30 = (20,-10)

+ x = Invalid

+ A1A = Invalid

+ B10A11 = Invalid

+ An empty does not affect

+ A10 = (10,-10)

Results (10,-10)

Example input: A10; S20; W10;d30; X A1A; B10A11;; A10;

Example output: 10. -10
