GPT Description

GPT Prompt Starters

• C . 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. Example 1: Input: nums = [1,2,3,1] Output: true Example 2: Input: nums = [1,2,3,4] Output: false
• Python. Find Duplicate Integer You are given an array of integers nums containing n + 1 integers. Each integer in nums is in the range [1, n] inclusive. Every integer appears exactly once, except for one integer which appears two or more times. Return the integer that appears more than once.
• Python.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.
• Given an array of strings strs, group the anagrams together. You can return the answer in any order.Example 1: Input: strs = ["eat","tea","tan","ate","nat","bat"] Output: [["bat"],["nat","tan"],["ate","eat","tea"]]
• Given an unsorted array of integers nums, return the length of the longest consecutive elements sequence. You must write an algorithm that runs in O(n) time.Example 1: Input: nums = [100,4,200,1,3,2] Output: 4 Explanation: The longest consecutive elements sequence is [1, 2, 3, 4].length is 4
