題目描述 - leetcode

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

C 解答

int findMaxConsecutiveOnes(int* nums, int numsSize) {
    int maxCount = 0;
    
    if (numsSize <= 0) {
        return 0;
    }
    
    int currentCount = 0;
    
    for (int i=0; i<numsSize; i++) {
        if (nums[i] == 0) {
            if (currentCount > maxCount) {
                maxCount = currentCount;
            }
            
            currentCount = 0;
        } else {
            currentCount += 1;
        }
        
        if ((i == numsSize - 1) && (currentCount > 0)) {
            if (currentCount > maxCount) {
                maxCount = currentCount;
            }
        }
    }
    
    return maxCount;
}

糾錯

解體的時候，走進了誤區，嘗試去計算 nums 指針指向的數組的長度，發現不能計算，因為只有一個指針是沒法判斷長度的，后來發現題目的參數給出了長度。
