题解：

func findMaxForm(strs []string, m, n int) int {
    dp := make([][]int, m+1)
    for i := range dp {
        dp[i] = make([]int, n+1)
    }
    for _, s := range strs {
        zeros := strings.Count(s, "0")
        ones := len(s) - zeros
        for j := m; j >= zeros; j-- {
            for k := n; k >= ones; k-- {
                dp[j][k] = max(dp[j][k], dp[j-zeros][k-ones]+1)
            }
        }
    }
    return dp[m][n]
}

func max(a, b int) int {
    if a > b {
        return a
    }
    return b
}
