1 or 2 to a 4-binary number n.input n3, n2, n1, n0 represent n.The input K is a control signal. The network should have outputs m3, m2, m1, m0, which represent the 4-bit binary number m.When k=0, m=n+1, when k=1, m=n+2. Assume that the input for which m>1111 will never occur. The input variable will available from switches.
