Electronic Circuit Connections

In designing an electronic circuit, components are connected via wires. Each connection is represented by pairs of components. Your task is to determine how many distinct subcircuits can be formed from a list of connections. A subcircuit is defined as a group of components that are interconnected directly or indirectly. Input format: - The first line contains an integer `c` (1 <= c <= 400) representing the number of connections. - The next `c` lines each contain two alphanumeric characters representing the connected components (e.g., 'R1 R2'). Output format: - A single integer representing the number of distinct subcircuits. Example: Input: 5 R1 R2 R2 R3 R4 R5 R6 R7 R8 R9 Output: 4 This means there are 4 distinct subcircuits: {R1, R2, R3}, {R4, R5}, {R6, R7}, and {R8, R9}.
