Secure Network Zones

In a computer network, nodes are either 'Encrypted' (type 1) or 'Plaintext' (type 0). A 'Secure Zone' is defined as a connected component of nodes where the number of Encrypted nodes is strictly greater than the number of Plaintext nodes. Given N nodes, their types, and M links added one by one, calculate the total number of Secure Zones remaining after all links are processed. Example: Input: 4 3 1 0 1 0 0 1 2 3 0 2 Initial: {0}(E), {1}(P), {2}(E), {3}(P). Secure: {0}, {2} (Total 2). Link 0-1: {0,1} (1E, 1P) -> Not secure. Link 2-3: {2,3} (1E, 1P) -> Not secure. Link 0-2: {0,1,2,3} (2E, 2P) -> Not secure. Final Secure Zones: 0
