You are given three positive integers: n, index, and maxSum. You want to construct an array nums (0-indexed) that satisfies the following conditions: nums.length == n nums[i] is a positive integer where 0 <= i < n. abs(nums[i] - nums[i+1]) <= 1
You have information about n different recipes. You are given a string array recipes and a 2D string array ingredients. The \(i\)-th recipe has the name recipes[i], and you can create it if you have all the needed ingredients from ingredients[i]. Ingred

调试题！ *2100 考虑答案由 \(\max(x),\min(x),\max(y),\min(y)\) 决定。 于是枚举一个位置，就拿 \(x\) 举例吧。 那么就要考虑 \([1,pos]\) 的累加最值，枚举当前 \(+-1\)，到当前枚举的位置的值，后缀的累加最值加上当前枚举的贡献，三者取个最值，那么就得到了。 有点难写和难调，注意 \((0,0)
