LeetCode: Max Consecutive Ones
这题最关键的是处理最开始连续1和最后连续1的方式,想到list一般在最前面加个node的处理方式,在最前面和最后面加0即可以很好地处理了
public class Solution {
public int findMaxConsecutiveOnes(int[] nums) {
int[] newNums = new int[nums.length+2];
newNums[0] = 0;
newNums[newNums.length-1] = 0;
for (int i = 1; i < newNums.length-1; i++) {
newNums[i] = nums[i-1];
}
int ans = 0;
int lastPos = 0;
for (int i = 0; i < newNums.length; i++) {
if (newNums[i] == 0) {
ans = Math.max(ans, i - lastPos);
lastPos = i;
}
}
return ans - 1;
}
}
