最长连续递增序列

贪心

var findLengthOfLCIS = function(nums) {
    let ans = 0;
    const n = nums.length;
    let start = 0;
    for (let i = 0; i < n; i++) {
        if (i > 0 && nums[i] <= nums[i - 1]) {
            start = i;
        }
        ans = Math.max(ans, i - start + 1);
    }
    return ans;
};

快慢指针

var findLengthOfLCIS = function(nums) {
    if (nums.length === 0) return 0;
    const n = nums.length;
    let left = 0, right = 1;
    let globalMaxLen = 1, maxLen = 1;
    while (right < n) {
        if (nums[right] > nums[left]) maxLen++;
        else {
            maxLen = 1;
        }
        left++;
        right++;
        globalMaxLen = Math.max(globalMaxLen, maxLen);
    }
    return globalMaxLen;
};
