I couldn't figure out how to design a circuit with this table:

inputs a b c d and outputs k m
a b c d _ k m
1 0 0 0 _0 0
1 0 0 1 _0 0
1 0 1 0 _0 0
1 0 1 1 _0 0
1 1 0 0 _1 0
1 1 0 1 _0 0
1 1 1 0 _0 0
1 1 1 1 _0 0
0 1 1 1 _0 0
0 1 1 0 _0 0
0 1 0 1 _0 0
0 1 0 0 _0 0
0 0 1 1 _0 1
0 0 1 0 _0 0
0 0 0 1 _0 0
0 0 0 0 _0 0

i mean for example, if a=1 and and bcd=011, when bcd=100, k will be 1,m=0 ; when in opposite case,from bcd=100 to bcd=011, m will be 1,k=0.

How can i make it?
