You are given an arraynumsof non-negative integers.numsis considered special if there exists a numberxsuch that there are exactlyxnumbers innumsthat are greater than or equal tox. Notice thatxdoes not have to be an element innums. Returnxif the array is special, otherwise, return-1. It ...
设置x从0开始遍历到len(nums),每次循环内再遍历nums数组,统计有多少个数大于等于x记为count,如果统计的结果大于x就break此次循环。遍历数组的循环结束后判断x是否等于count,如果是就返回x,不是的话就返回-1。 时间复杂度:O(n*n) 空间复杂度:O(1) 代码 classSolution:defspecialArray(self,nums:List[int])->...
如果最终循环结束依旧找不到特征值,返回 -1 。 代码# Go package leetcode import "sort" func specialArray(nums []int) int { sort.Ints(nums) x := len(nums) for _, num := range nums { if num >= x { return x } x-- if num >= x { return -1 } } return -1...
Given an arraynums(consisting ofonlyintegers0,1, and2), returnthenumber of different subsequencesthat are special. Since the answer may be very large,return it modulo109+ 7. Asubsequenceof an array is a sequence that can be derived from the array by deleting some or no elements without cha...
