I need a code in c++ about reading a text file into a hash table. (the content of the text file is integer). By assigning the line number to be the key and line contents into an array. After that do the comparison as described in the body.
Buget $30-250 USD
Job Description:
I have a file of 5MB and I want to hash it to hash table. It is integers where the key is the line number and the value is an array of the content in that line. The data in the file looks like this.
key = 1 Neighbors 1 3 5
key = 2 Neighbors 2 4 5
key = 3 Neighbors 3 2 1
key = 4 Neighbors 6 4 2
1 3 5
2 4 5
3 2 1
6 4 2
So, for first line Key = 1, and Value = {1,3,5} The problem is that I want the line number to be my key and the data to be in an array.
I want to store this file in a hash table. Then running nested loops where it iterate through all keys (number of lines), for each key retrieve the value (set of Neighbors S[]), For each neighbor s in S do retrieve all lines that match with neighbors. Then check if line x is in the Neighbors of these Neighbors. If yes True++, if no False++.
Assume k =3
The file looks like that
X_1 X_2 X_3
Read 3-NN file into hashtable
Hash-table T=<key,value>
Key = B = line number
Value = {X_1, X_2, X_3}
Next run the following nested loop
True=0; False = 0;
iterate through all keys in T
for each key s belong to S retrieve the set of Value (in the example above S={X_1, X_2, X_3})
For each Value X_i do
let the Value X_i be the Key and retrieve all retrieve sets
( so it will return the Value of line X_1 and line X_2 and line X_3)
Check if B is in Value is in the retrieve sets.
True ++;
else
False ++;
Summary
Each line is a point and the line content is the neighbors. For a point x that has X_i neighbors
checking is X_i neighbors considering x from their neighbors. if yes increas true if no increase false.
I did it in a two dimensional matrix and it works fine but my data is huge so matrix is not a good solution.
As shown in the attached file.
