僅作備份 效率太低了

/*** @param {number[]} nums* @param {number} target* @return {number}*/ var searchInsert = function(nums, target) {let len = nums.length;function findIndex(start = 0, end = len - 1){if(nums[start] >= target){return start;}if(nums[end] === target){return end;}if(nums[end] < target){return end + 1;}let middle = parseInt((start + end) / 2);if(target === nums[middle]){return middle;}if(middle > 0 && target > nums[middle - 1] && target < nums[middle]){return middle;}if(middle < (len - 1) && target > nums[middle] && target < nums[middle + 1]){return middle + 1;}if(target < nums[middle]){return findIndex(start, middle);}else{return findIndex(middle, end);}}return findIndex(); }; 復(fù)制代碼
