Given an integer number n, return the difference between the product of its digits and the sum of its digits. Example 1: Input: n = 234 Output: 15 Explanation: Product of digits = 2 * 3 * 4 = 24 Sum of digits = 2 + 3 + 4 = 9 Result = 24 - 9 = 15 ...
先排序,然后调用二分查找函数获取比 k 小的第一个数的下标 end,设置 start = 0,当 start < end 时做循环,计算 nums[start] + nums[end] 的值 Sum,判断 Sum 和 k 的关系,如果 Sum >= k 就把 end 减1,否则 start + 1 后更新和的最大值 maxsum。循环结束后返回 maxsum。 时间复杂度:O(nlogn...
