Please find the full code,
Sorry, I'm asking what problem are you solving, what the
program should do, what is its idea. Not what code you have
written.
Hi,
I am trying to implement data dictionary compression, and below
is the function of the program,
Function read:
This function read a csv file which contains 3 column as and
stores the value of each column in an array Col1: Array1 (Ucol1),
Col2: Array2 (Ucol2), Col3: Array3(Ucol3) and returns the data.
CSV file content:
Miller America 23
John India 42
Baker Australia 21
Zsuwalski Japan 45
Baker America 45
Miller India 23
Function Main
This function receives the data from the function read.
Creates an array based of the function return type – (
typeof(read()[i]) Data );
Sorts the data and removes the duplicates and stores the data in
the above array.
Then using “countUntil” function we can accomplish the data
dictionary compression.
Result
The above file will be stored as
Data File:
Data-Col1.txt which contains [Baker, John, Miller, Zsuwalski]
Data-Col2.txt which contains [America, Australia , India, Japan]
Data-Col3.txt which contains [21, 23, 42, 45]
Index File:
Index-Col1.txt which contains [2, 1, 0, 3, 0, 2]
Index -Col2.txt which contains [0, 2, 1, 3, 0, 2]
Index -Col3.txt which contains [1, 2, 0, 3, 3, 1]
The program works for a single column.
From,
