The first line of input contains an integer T denoting the no of test cases. Then T test cases follow. Each test case contains two lines. The first line of each test case contains an integer N. Then in the next line are N space separated values of the array A. Output: For each tes...
[GeeksForGeeks] Minimum length unsorted subarray, sorting which makes the array sorted Given an array, find the minimum length unsorted subarray. After soring this unsorted subarray, the whole array is sorted. Example, if the input array is [10, 12, 20, 30, 25, 40, 32, 31, 45, 50, ...
System.out.println("CRC32 checksum for input string is: "+ checksumValue); } } Output: CRC32 checksum for input string is: 3564377865 This was an example of how to calculate the CRC32 checksum of a byte array in Java. Do you want to know how to develop your skillset to become aJ...
Both array and ArrayList are two important data structures in Java and are frequently(经常) used in Java programs. Even though ArrayList is internally(在内部) backed by an array, knowing the difference between an array and an ArrayList in Java is critical(至关重要的) for becoming a good Java...

If there are n elements in array, then floor(n/2)'th element should be chosen as root and same should be followed recursively. Solution. 1. get the middle element and create root node N. 2. recursively create a balanced BST from the left half of the array and set its root as N's...
