B'You are given an array a consisting of n integer numbers. You have to color this array in k colors in such a way that: Obviously, such coloring might be impossible. In this case, print "NO". Otherwise print "YES" and any coloring (i.e. numbers c_1, c_2, ... c_n , where 1 <= c_i <= k and c_i is the color of the i -th element of the given array) satisfying the conditions above. If there are multiple answers, you can print any. The first line of the input contains two integers n and k ( 1 <= k <= n <= 5000 ) -- the length of the array a and the number of colors, respectively. The second line of the input contains n integers a_1, a_2, ... , a_n ( 1 <= a_i <= 5000 ) -- elements of the array a . If there is no answer, print "NO". Otherwise print "YES" and any coloring (i.e. numbers c_1, c_2, ... c_n , where 1 <= c_i <= k and c_i is the color of the i -th element of the given array) satisfying the conditions described in the problem statement. If there are multiple answers, you can print any. In the first example the answer 2~ 1~ 2~ 1 is also acceptable. In the second example the answer 1~ 1~ 1~ 2~ 2 is also acceptable. There exist other acceptable answers for both examples. '...
