    Problem Description
    Wangpeng has N clothes, M pants and K shoes so theoretically he can have N×M×K different combinations of dressing.
    One day he wears his pants Nike, shoes Adiwang to go to school happily. When he opens the door, his mom asks him to come back and switch the dressing. Mom thinks that pants-shoes pair is disharmonious because Adiwang is much better than Nike. After being asked to switch again and again Wangpeng figure out all the pairs mom thinks disharmonious. They can be only clothes-pants pairs or pants-shoes pairs.
    Please calculate the number of different combinations of dressing under mom’s restriction.
     
    
    Input
    There are multiple test cases.
    For each case, the first line contains 3 integers N,M,K(1≤N,M,K≤1000) indicating the number of clothes, pants and shoes.
    Second line contains only one integer P(0≤P≤2000000) indicating the number of pairs which mom thinks disharmonious.
    Next P lines each line will be one of the two forms“clothes x pants y” or “pants y shoes z”.
    The first form indicates pair of x-th clothes and y-th pants is disharmonious(1≤x≤N,1 ≤y≤M), and second form indicates pair of y-th pants and z-th shoes is disharmonious(1≤y≤M,1≤z≤K).
    Input ends with “0 0 0”.
    It is guaranteed that all the pairs are different.
     
    
    Output
    For each case, output the answer in one line.

    题意:略。
    
    思路:
    简单的组合问题,注意加上重复的就是(在一个点上左边的线乘以右边的线的个数)
