[Huawei on-machine exercises] 9. Coordinate movement

Topic

Develop a coordinate calculation tool, a for moving to the left, D for moving to the right, W for moving up, and s for moving down. Moves from the (0,0) point, reads some coordinates from the input string, and outputs the final input to the output file.

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

The following is a simple example:

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)

Title Category: String
Difficulty: Intermediate
Operating time limit: 10Sec
Memory Limit: 128MByte
Stage: Pre-employment practice
Input:
Line string

Output:
Final coordinates, to, separating

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

Sample output:
10,-10
