Increment Large Integer Array by One

🚀 Day 33/150 of hashtag#150DaysOfDSA 📌 Task: Sqrt(x) Given a non-negative integer x, return the square root of x rounded down to the nearest integer. The returned integer should be non-negative as well. You must not use any built-in exponent function or operator. #150DaysOfCode #DSA #CPP #Algorithms #CodingJourney #LeetCode #ProblemSolving

🚀 Day 28/150 of hashtag#150DaysOfDSA 📌 Task: Contains Duplicate Given an integer array nums, return true if any value appears at least twice in the array, and return false if every element is distinct. #150DaysOfCode #DSA #CPP #Algorithms #CodingJourney #LeetCode #ProblemSolving

🚀 Day 46/150 of hashtag#150DaysOfDSA 📌 Task: Set Mismatch You have a set of integers s, which originally contains all the numbers from 1 to n. Unfortunately, due to some error, one of the numbers got duplicated, resulting in one repeated number and one missing number. You are given an integer array nums representing this incorrect set. Find the number that occurs twice and the number that is missing, and return them in the form of an array. #150DaysOfCode #DSA #CPP #Algorithms #CodingJourney #ProblemSolving

🚀 Day 49/150 of hashtag#150DaysOfDSA 📌 Task: Two Sum Given an array of integers nums and an integer target, return indices of the two numbers such that they add up to target. You may assume that each input would have exactly one solution, and you may not use the same element twice. You can return the answer in any order. #150DaysOfCode #DSA #CPP #Algorithms #CodingJourney #ProblemSolving

🚀 Day 39/150 of hashtag#150DaysOfDSA 📌 Task: Happy Number Write an algorithm to determine if a number n is happy. A happy number is defined by the following process: Starting with any positive integer, replace the number by the sum of the squares of its digits. Repeat the process until the number equals 1 (where it will stay), or it loops endlessly in a cycle which does not include 1. Return true if n is a happy number, and false if not. #150DaysOfCode #DSA #CPP #Algorithms #CodingJourney #ProblemSolving

🚀 Day 48/150 of hashtag#150DaysOfDSA 📌 Task: Valid Perfect Square Given a positive integer num, return true if num is a perfect square or false otherwise. A perfect square is an integer that is the square of an integer (i.e., the product of an integer with itself). You must not use any built-in library function, such as sqrt. #150DaysOfCode #DSA #CPP #Algorithms #CodingJourney #ProblemSolving

🚀 Day 43/150 of hashtag#150DaysOfDSA 📌 Task: Find First and Last Position of Element in Sorted Array Given an array of integers nums sorted in non-decreasing order, find the starting and ending position of a given target value. If target is not found in the array, return [-1, -1]. You must write an algorithm with O(log n) runtime complexity. #150DaysOfCode #DSA #CPP #Algorithms #CodingJourney #ProblemSolving

🚀 Day 42/150 of hashtag#150DaysOfDSA 📌 Task: Binary Search Given an array of integers nums which is sorted in ascending order, and an integer target, write a function to search target in nums. If target exists, then return its index. Otherwise, return -1. You must write an algorithm with O(log n) runtime complexity. #150DaysOfCode #DSA #CPP #Algorithms #CodingJourney #ProblemSolving

🚀 Day 34/150 of hashtag#150DaysOfDSA 📌 Task: Search Insert Position Given a sorted array of distinct integers and a target value, return the index if the target is found. If not, return the index where it would be if it were inserted in order. You must write an algorithm with O(log n) runtime complexity. #150DaysOfCode #DSA #CPP #Algorithms #CodingJourney #LeetCode #ProblemSolving

🚀 Day 35/150 of hashtag#150DaysOfDSA 📌 Task: Linked List Creation (Advanced DSA) Create a singly linked list by inserting multiple nodes at the end and display the complete list. Each node should store an integer value and a pointer to the next node. #150DaysOfCode #DSA #CPP #Algorithms #CodingJourney #ProblemSolving
