Question

A linked list is formed from the objects of the class Cell. The class structure of the Cell is given below:

class Cell
{
    char m;
    Cell right;
}

Write an Algorithm OR a Method to print the sum of the ASCII values of the lower case alphabets present in the linked list. 

The method declaration is as follows:

void lowercase(Cell str)

Answer 1

Algorithm to find the sum of ASCII values of lowercase letters in a linked list

1. Begin from the head node of the linked list.
2. Set a variable sum to 0.
3. Repeat the following steps until the current node becomes null:
   1. Check whether the character stored in the current node lies between 'a' and 'z'.
   2. If it is a lowercase letter, add its ASCII value to sum.
   3. Move the pointer to the next node in the list.
4. Once the traversal is complete, display the value of sum.
