string = input().split(';')


x,y = 0, 0
for n in string:
    # print(n, x, y)
    if n == '':
        continue
    elif not n[0] in ['A', 'S', 'W', 'D']:
        continue
    else:
        try:
            step = int(n[1:])
            # print(step)
            if n[0] == 'A':
                x -= step
            elif n[0] == 'D':
                x += step
            elif n[0] == 'W':
                y += step
            else:
                y -= step
        except:
            continue
    
print('{},{}'.format(x, y))
