The time complexity of this solution isO(n), wherenis the number of digits in the integer. Adding to aHashSetand checking its size are bothO(1)operations, but we still have to iterate through each digit. 4. Using Stream API Java’sStream APIprovides a concise and modern solution to coun...
Given a non-negative integer n, count all numbers with unique digits, x, where 0 ≤ x < 10n. Example: Given n = 2, return 91. (The answer should be the total numbers in the range of 0 ≤ x < 100, excluding[11,22,33,44,55,66,77,88,99]) 解题思路: This problem can also b...
[LeetCode] 2364. Count Number of Bad Pairs You are given a 0-indexed integer array nums. A pair of indices (i, j) is a bad pair if i < j and j - i != nums[j] - nums[i]. Return the total number of bad pairs in nums. Example 1: Input: nums = [4,1,3,3] Output: 5...
