Question

There is a array of 100 blocks, here each block contains one color and this color comes from an array of characters a,b,c,…,z randomly.

Ex:
a b d e g i h f d a

Now you have to write a program, that will return sorted array with following conditions.

1. Following swapping order should be follow.

Character maximum swap

a 1

b 2

c 3

… …

z 26

Output:
a a b d d e f h g i

I have used the following methods.

//return no of blocks

int getNoOfBlocks();

//return the alphabet at particular block

char getData(int);

//swap the value

void swapBlock(int, int);

void arrangeBlocks(void)

{

int size = getNoOfBlocks();

for(int i = 0 ; i < size; i++)

    {

        int min = getData(i)-97;

        int pos = 0;

        int ascii = 0;

        for(int j = i + 1; j < size; j++)

            {

               ascii = getData(j)-97;

                if(min > ascii)

                  {

                      min = ascii;

                      pos = j;

                  }

            }

        swapBlock(i, pos+1);

    }

}

Answer 1

You are swapping the wrong elements, it should be:

  swapBlock(i, pos);

Also your first loop is wrong, it should be:

  for(int i = 0 ; i < size - 1; i++)
