{"idx": 24, "Skill": "Code Generation", "Difficulty": 6, "Instruction": "You can write C# code. Given an unsorted array of integers, sort it using quicksort algorithm. For example, if the array is [10, 80, 30, 90, 40, 50, 70], then after sorting it using quicksort, it should be [10, 30, 40, 50, 70, 80, 90]. Quicksort is a divide-and-conquer algorithm that works by choosing a pivot element from the array and partitioning the array into two subarrays such that all elements less than or equal to the pivot are in the left subarray and all elements greater than the pivot are in the right subarray. Then it recursively sorts the left and right subarrays until the array is sorted."}

The longest common subsequence (LCS) between two strings is the longest subsequence that is common to both strings. For example, if the two strings are \u201cABCDGH\u201d and \u201cAEDFHR\u201d, then the LCS is \u201cADH\u201d with length 3. Please use Java to solve the above question."}
