it's not about being the best it's about being better than yesterday
Isomorphic strings are two strings where characters at the same index in both strings can be replaced to make the strings equal. In other words, if we can replace all occurrences of one character in the first string with another character and obtain the second string, and vice versa, then the strings are isomorphic. In…
Understanding the Problem: Before we dive into the code, let’s take a moment to understand the problem at hand. We’re given an array of integers and a value k, representing the maximum number of elements we can remove from the array. Our goal is to determine the least number of unique integers remaining in the…
Understanding the Problem Given an array of strings strs, our task is to group the strings that are anagrams of each other together and return them as a list of lists. Approach To efficiently group anagrams, we can leverage the properties of anagrams. Two strings are anagrams of each other if they have the same…
String closeness, in the context of this problem, involves evaluating whether two words can be considered “close” by meeting certain criteria. The criteria include having the same set of characters and the same frequency distribution of those characters. The closeStrings method endeavors to address this challenge. Unpacking the Solution Basic Check: The basicCheck method ensures…
Introduction: The problem involves identifying pairs of indices in an array that satisfy certain conditions, with a specific mathematical operation. This blog will discuss the problem, the provided solution, and break down the code for a better understanding. Problem Overview: The goal is to find the count of such nice pairs of indices. Due to…
Given an integer array nums and an integer k, return the k most frequent elements. You may return the answer in any order. Example 1: Input: nums = [1,1,1,2,2,3], k = 2 Output: [1,2] Example 2: Input: nums = [1], k = 1 Output: [1] Constraints: 1 <= nums.length <= 105 -104 <= nums[i] <= 104 k is in the range [1, the number…
Understanding the Problem The problem statement is as follows: Given an array of words, return the k most frequent words. If there are multiple answers, return answers in their lexicographical order The Code We’ll break down the code into sections to understand how it works. Custom Data Structure: Frequency First, we define a custom class called…
