python代码，WA了第10个点

算法应该没问题

# 90pts
def ele():
    flag = 0
    cnt = w = l = 0
    for ch in tot:
        if ch == 'E':
            break
        if ch == 'W':
            w += 1

            l += 1
            cnt += 1
        if (w >= 11 or l >= 11) and abs(w-l) >= 2 :
            print(w, ":", l, sep='')
