# 初始输入
n = input().strip().split(';')
m = ['A','D','S','W'].
# 对输入进行处理
a = [_ for _ in n if len(_) > 1]
b = []
c = {}
x,y = 0,0
# 判断有效坐标
for i in a :
if i[0] in m and i[1:].isnumeric() :
b.append(i)
# 对有效坐标保存成字典格式
for i in b :
c[i[0]] = c.get(i[0],0) + eval(i[1:])
# 遍历 字典进行判断
for i,j in c.items():
if i == 'A':
x -= j
elif i == 'D':
x += j
elif i == 'W':
y += j
elif i == 'S':
y -= j
print(f'{x},{y}')
