Thread: Loop to note position of lowest number

Hi guys,

I have a password key which is "password12Qcb6z:!sh:&BYztwYTPM" which i have repeating a number of times in a 1d array.

What i am trying to create an array where numbers are assigned starting with 1, and they are assigned first by alphabetical order, and second, where the same letter appears twice, by position in the word.


for example:

C O N V E N I E N C E
1 10 7 11 3 8 6 4 9 2 5


my key is alot longer than "CONVENIENCE" its roughly 328 characters long ("password12Qcb6z:!sh:&BYztwYTPM" repeated ). so i have a 1d int array array which i want to map out 1-328 following the rule above starting wit the lowest character in its ascii values 32 = SPACE to ~ = 127. so i then have a array mapping out 1-328 ...


I have this code so far

int v=0, count=0, r=32; // 33 is the first usable ascii character in test file 
int[] colprintorder = new int[numberofcols];
 
 
while(r<=127) // loop unit last usable ascii char
{
    for(int i=0;i<passwordinbyte.length;i++) // go through each cell of  the array
    {
 
       if (r == passwordinbyte[i]) // if the value of r is the same as what is in passwordinbyte  map its position storing in colprintorder
       {
       colprintorder[count] = i ;
       count++; // next cell in the array
       }
    }  
 r++; // look for the next characters ascii value  32-127
}
 
for(int a=0; a<colprintorder.length; a++) // print out colprint order
{
   System.out.println( colprintorder[a] + " " );
}
 
System.out.println("lengthhrr" +passwordinbyte.length);

Here is my output using the code snippet above:

it appears theres somthing wrong with my code but i dont know what can you guys help me ?


thank you

Ok, I'm a little confused (maybe this is above me or something).

So, you are wanting to get the ASCII values of all of the characters, then determine, based on their ASCII values, which come first, second, third, ect.

If so, I am unsure why you have all that code. You can convert a String to a char[] using the String.toCharArray() method, then sort the char[] with the Arrays.sort(char[]) method, then do whatever with the sorted array.

When I input CONVENIENCE in the code below:

import java.util.Arrays;
 
public class ASCIITesting
{
    public static void main(String[] args)
    {
    	String input = "CONVENIENCE";
    	char[] charArr = input.toCharArray();
    	Arrays.sort(charArr);
    	for(int i=0;i<charArr.length;i++)
    		System.out.print(Character.toString(charArr[i]));
    }
}

It outputs:

CCEEEINNNOV

which is the word sorted based on each character's ASCII value.
Similarly, if I input password12Qcb6z:!sh:&BYztwYTPM it outputs:

!&126::BMPQTYYabcdhoprssstwwzz

Am I totally off?
