HashMap<Integer, List<Integer>> 操作示例
如何遍历哈希表的键值对：
public int majorityElement(int[] nums) {
Map<Integer, Integer> counts = countNums(nums);
Map.Entry<Integer, Integer> majorityEntry = null;
for (Map.Entry<Integer, Integer> entry : counts.entrySet()) {
if (majorityEntry == null || entry.getValue() > majorityEntry.getValue()) {
majorityEntry = entry;
}
}
return majorityEntry.getKey();
}
