(Java) implement the radix sort that can sort a file contains either all positive integers or a file
contains mixture of positive and negative integers.
1. Input: one input txt file. //-1 for hard code file name.
inFile (use args [0]): a text file contains a list of integers (may contain negative numbers)
2. Outputs:
a) outFile1(args [1]):
- The input data, one data per text-line.
- The entire hash table after each iteration (move from one hash table to the other hash table.
- Print the result of the sorted data, one data per text-line.
b) deBugFile (use args [2]): For all debugging prints.
3. Data Structures
- listNode class
-(int) data
-(listNode) next
Methods:
- constructor (data)//create a listNode node for data and make sure assign nodes next null
- LLQueue class
-(listNode) head
-(listNode) tail
Methods:
- constructor(...)
- insertQ (table, index, newNode)// insert the newNode after the tail of hashTable[table][index].
// hashTable[table][index].tail.next newNode
// hashTable[2][tableSize].tail newNode
-(listNode *) deleteQ (...)// if Q is not empty, deletes and returns the node after the dummy
-(bool) isEmpty (...)// Returns true if tail == head, returns false otherwise.
- printQueue (whichTable, index, File)// File can be outFile1 or deBugFile.
// Print to File the entire linked list in hashTable[whichTable][index].
// For example, if whichTable is 1 and index is 6, then print
Table [1][6]: (-999,33)(33,36)(36,18)............(13, NULL) NULL
- A RadixSort class:
-(int) tableSize // set to 10.
-(LLQueue) hashTable[2][tableSize]//21D arrays (size of 10) of linked listqueues with dummy nodes.
// Initially, create a new listNode for each hashTable[i][j] to point to and set hashTable[i][j]'s head and
// tail point to the dummy node.
-(int) data
-(int) currentTable // either 0 or 1
-(int) previousTable // either 0 or 1
-(int) maxLength // the number of digits of the largest integer to control the number of iterations of Radix sort
-(int) offSet // if there is no negative integer in the data, offSet will be zero; otherwise, the offset is the absolute
//value of the smallest negative integer in the data;
// the offSet will add to each data before radix sort and subtract off afterward.
-(int) digitPosition // The digit position of data that is currently processing, initialize to 0.
-(int) currentDigit // the digit which is currently used for sorting.
Methods:
- constructor ()// Creates hashTable[2][tableSize].
// Use loops to create LLQueue for each hashTable[i][j], i =0 to 1 and j =0 to 9, where
// make a new listNode (as dummy node) for each hashTable[i][j] point to and initially, head and tail are
// also point to dummy node.
- preProcessing (...)// Read from input file; determine the largest and smallest integers in the file
// and establishes offset. See algorithm below. You may include this method in constructor!
- RSort (...)// Performs Radix sort; sorts data dogot from right-to-left. See algorithm below.
// The algorithm is exactly the same as taught in class.
-(int) getLength (data)// Determines and returns the length of data.
//** suggestion: convert data to string, then returns string length.
-(int) getIndex (data, position)//This method is the hash function that determines and returns the digit at the
// position of data, which is the index of the hash table for insertion. For example,
// if data is 31456, length is 5; data position 0 is 6; 1 is 5; 2 is 4; 3 is 1 and 4 is 3
- printTable (whichTable, File)// On your own!
// Call printQueue (...) to print each none empty queue in hashTable[whichTable] out to File.
- printSortedData (whichTable, outFile1)// Output the final result of sorted data.
// Print nodes data in none empty queue in hashTable[whichTable][index], index =0 to tableSize
//10 numbers per text-line with space in between two numbers.
//*** make sure to subtract offSet before printing the data.
4. main()
Step 0: inFile open via args [0]
outFile1 open via args [1]
deBugFile open via args [2]
hashTable[2][tableSize] create by RadixSort constructor
Step 1: preProcessing (inFile, deBugFile)
Step 2: close inFile
reopen inFile.
Step 3: RSort (inFile, outFile1, deBugFile)
Step 4: close all files
5. preProcessing (inFile, deBugFile)
Step 0: deBugFile "** Entering preProcessing ()"
negativeNum 0
positiveNum 0
Step 1: data read one integer from inFile
if data < negativeNum
negativeNum data
if data > positiveNum
positiveNum data
Step 2: repeat step 1 until inFile is empty
Step 3: if negativeNum <0
offSet abs (negativeNum)
else
offSet 0
Step 4: positiveNum positiveNum + offset
maxLength getLength (positiveNum)
Step 5: deBugFile In preProcessing (): negativeNum=, offSet=, positiveNum=, maxDigits = print values
Step 6: deBugFile Leaving preProcessing ()
