- Program this in java the state and variable display must be:Unsorted Partition Reference Index: 0, Traversing Index: 7, Current Traversing Index Value: mango, Next Index Value: plum, Swapping Condition: FalseCurrent Array: ['apple', 'avocado', 'orange', 'banana', 'strawberry', 'pineapple', 'plum', 'mango'] The input:["apple", "avocado", "orange", "banana", "strawberry", "pineapple", "plum", "mango"]Note:The sorted partition is on the left side. Then, the order is increasing based on the number of vowels of a string.the output must be like this:['plum', 'apple', 'strawberry', 'mango', 'orange', 'banana', 'avocado', 'pineapple']File System: It is highly useful in file system handling where for example the file allocation table contains a sequential list of locations where the files is split up and stored on a disk. Remember that overtime it is hard for an OS to find disk space to cover the entire file so it usually splits these up into chunks across the physical hard drive and stores a sequential list of links together as a linked list. Write an algorithm for the above problem and analyse the efficiency of the algorithm.Program in Java: topic: insertion sort The state and variable display: Unsorted Partition Reference Index: 7, Traversing Index: 1, Current Traversing Index Value: avocado, Condition Value Index: 0 Current Condition Value: apple, Swapping Condition: FalseCurrent Array: ['apple', 'avocado', 'orange', 'banana', 'strawberry', 'pineapple', 'plum', 'mango'] The Input must be:["apple", "avocado", "orange", "banana", "strawberry", "pineapple", "plum", "mango"]The assumptions and conditions: Sorted partition is on the right side.The order is increasing alphabetically but the strings that has an odd length should be the first to be sorted then the strings with the even length goes next The result or Output must be:['apple', 'avocado', 'mango', 'pineapple', 'banana', 'orange', 'plum', 'strawberry']

Tables neededo Books Id Book Name Author Name…object of type streambuf. This object may represent a memory block that acts as an intermediary When we operate with file streams, these are associated to an internal between the stream and the physical file. For example, with an ofstream, each time the member function put (which writes a single character) is called, the character may be inserted in this intermediate buffer instead of being written directly to the physical file with which the stream is associated. O batch O switch binary O bufferLinear list directory structures have the disadvantage that you must search an entire linked list to ensure that a new file doesn't match a name already in the directory.

- In an executable object file that is in executable and linkable format (ELF), which section defines the addresses of the stack and the heap? A. The data section B. The .text section C. These addresses are not defined in the executable object file. Instead, they are assigned by the operating system when the program is loaded in to me D. These addresses are not defined in the executable object file. Instead, they are assigned by the user when the program is running in memory.
