Find out distance between similar characters in a string

Here given code implementation process.

// C program

    int visit[255];

    // Loop controlling variable
    int i   = 0;
    // Resultant variable
    int sum = 0;    

    // Set the initial default values
    // 255 indicates all possible alphabet character
    for (i = 0; i < 255; ++i)
