Tina has recently been introduced to a programming concept called Hashing.
Hashing is the transformation of a string of characters into a usually shorter fixed-length value or key that represents the original string.
Hashing is used to index and retrieve items in a database because it is faster to find the item using the shorter hashed key than to find it using the original value. sources: Internet
As a homework, her teacher has given a string and asked her to find no of strings she can make using each of the alphabet as starting character. Though she has already solved the question, she isn’t sure if her answers are correct.
Help her by telling the correct answer of all the questions.
For each alphabet, print the remainder obtained by dividing the answer by 1000000007.
Input:
Only line of Input has a single string.
Output:
26 integers denoting no of strings that can be made by using each of the alphabet as starting character.#include <stdio.h>
#include <string.h>

int len=strlen(string);

printf("%d ",arr[i]);
return 0;
