## 解题思路
|
|
|
|
|
|
|
|
|
|
```java
|
|
|
|
|
public boolean isContinuous(int[] nums) {
|
|
|
|
|
|
|
|
|
|
if (nums.length < 5)
|
|
|
|
|
return false;
|
|
|
|
|
|
|
|
|
|
Arrays.sort(nums);
|
|
|
|
|
|
|
|
|
|
// 统计癞子数量
|
|
|
|
|
int cnt = 0;
|
|
|
|
|
for (int num : nums)
|
|
|
|
|
if (num == 0)
|
|
|
|
|
cnt++;
|
|
|
|
|
|
|
|
|
|
// 使用癞子去补全不连续的顺子
|
|
|
|
|
for (int i = cnt; i < nums.length - 1; i++) {
|
|
|
|
|
if (nums[i + 1] == nums[i])
|
|
|
|
|
return false;
|
|
|
|
|
cnt -= nums[i + 1] - nums[i] - 1;
|
|
|
|
|
}
|
|
|
|
|
|
|
|
|
|
return cnt >= 0;
|
|
|
|
|
}
|
|
|
|
|
```
