Given a binary array, find the maximum number of consecutive 1s in this array.
Example 1:
Input: [1,1,0,1,1,1]
Output: 3
Explanation: The first two digits or the last three digits are consecutive 1s.
The maximum number of consecutive 1s is 3.
Note:
The input array will only contain 0 and 1.
The length of input array is a positive integer and will not exceed 10,000
题意:输出最大的连续的1,例如连续有3个1就输出3
思路:创建一个一维数组保存每段连续的1的个数,用Arrays.sort排序(默认从小到大),输出最大值(即最后一个)
知识点:
1、复习Arrays.sort,将数组排序,默认从小到大
2、用JAVA创建一个数组,该数值所有的初始值都是0
class Solution {
public int findMaxConsecutiveOnes(int[] nums) {
int len = nums.length;//省时
int[] out = new int[len];
int x = 0;
for(int i=0;i<len;i++){
if(nums[i] == 1){//注意是if不是while,因为外面有一个for循环遍历数组了
out[x] += 1;//out[]初始值是0,直接+1就行
}else{
x += 1;
}
}
Arrays.sort(out);//默认从小到大
return out[out.length-1];//即数组的最后一位
}
}
