[Solved] You are given an integer array nums. You are initially positioned at the array’s first index, and each element in the array represents your maximum jump length at that position. Return true if you can reach the last index, or false otherwise.
[Solved] Given an integer array nums, find the contiguous subarray (containing at least one number) which has the largest sum and return its sum.
[Solved] Implement pow(x, n), which calculates x raised to the power n (i.e., xn).
[Solved] Given an array of strings strs, group the anagrams together. You can return the answer in any order. An Anagram is a word or phrase formed by rearranging the letters of a different word or phrase, typically using all the original letters exactly once.
[Solved] You are given an n x n 2D matrix representing an image, rotate the image by 90 degrees (clockwise). You have to rotate the image in-place, which means you have to modify the input 2D matrix directly. DO NOT allocate another 2D matrix and do the rotation.
[Solved] Given a collection of numbers, nums, that might contain duplicates, return all possible unique permutations in any order.
[Solved] Given an array nums of distinct integers, return all the possible permutations. You can return the answer in any order.
[Solved] Given an array of non-negative integers nums, you are initially positioned at the first index of the array. Each element in the array represents your maximum jump length at that position.
