/**
 * Wow. Idk how to express my shock when i saw that interactive problems can be like
 * this! So we basically have to write a program that outputs the correct 0/1 across
 * all images. First thought: we can't do compare each pair of rows, this takes about
 * 19900 (>10000) calls.
 * We don't have "for" or "if" statements... Hmm. I don't wanna do int addition /
 * subtraction using logic gates too... Well, in general we don't have much calls
 * available, so perhaps in a lot of calls the num of input isn't small. Nah...
 * 
 * I'd like to note down my final thought. Suppose that c_1, c_2, ..., c_m are 0/1
 * bits representing whether column i has a black cell. Let's put away the case of
 * only one 1. Let d_i := c_1 ^ c_2 ^ ... ^ c_i, so the number of 1s in (d_i) is 
 * the horizontal dist. Similarly we can do this for the vertical direction, then 
 * it suffices to count the num of 1s in some cells and check if it's K.
 * Unfortunately, the only sol i have is to do a dp which requires an additional
 * K(H+W) cells. Too much... (I'll submit a brute-force version in impl1)
 * 
 * This think this is a problem where scoring partials is easy, but getting full is
 * hard.
 * 
 * Number of calls:	2HW     (i think. i haven't checked)
 * Number of reads:	6HW
 * Implementation 1         (Solves [S1-3], [S5], [S6-7])
