Team Decisions

For each problem, three team members vote whether they know the solution. Return how many problems should be solved if a problem is accepted only when at least two members vote 1.

Examples

Example 1
Input:
votes = [[1, 1, 0], [1, 1, 1], [1, 0, 0]]
Output:
2

Explanation: The first two problems have at least two votes.

Approach hint

Count the number of 1s in each row.

Common mistake

Skipping assumptions, edge cases, or trade-offs can make an otherwise good answer feel incomplete.
