The size of theHashSetafter iteration gives us the count of unique digits. 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. Usi...

[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....
Use std::to_string and std::string::size Functions to Count Number of Digits in a Number in C++ The most straightforward way to count the number of digits in a number is to convert it to the std::string object and then call a built-in function of the std::string to retrieve a cou...
