题解 | #坐标移动#

'''
解题思路：
定义一个将命令翻译成坐标移动的函数 x,y = fn(command)，当command为空或不合法时，返回0,0
'''
def fn(s):
    if s:
        tmp = s[1:]
        if s[0]=='A' and tmp.isdigit():
            return -int(tmp),0
        elif s[0]=='S' and tmp.isdigit():
            return 0,-int(tmp)
        elif s[0]=='W' and tmp.isdigit():
            return 0,int(tmp)
        elif s[0]=='D' and tmp.isdigit():
            return int(tmp),0
        else:
            return 0,0
    else:
        return 0,0

while 1:
    try:
        pass

        L = input().strip().split(';')
        #print(L)
        M = []
        for s in L:
            M.append(fn(s))
        #print(M)

        x=0
        y=0
        for s in M:
            x += s[0]
            y += s[1]
        print(str(x)+','+str(y))

    except:
        break
