We will call a string that can be obtained by concatenating two equal strings an even string.
For example, xyzxyz
and aaaaaa
are even, while ababab
and xyzxy
are not.
For a non-empty string $S$, we will define $f(S)$ as the shortest even string that can be obtained by appending one or more characters to the end of $S$.
For example, $f($abaaba
$)=$abaababaab
.
It can be shown that $f(S)$ is uniquely determined for a non-empty string $S$.
You are given an even string $S$ consisting of lowercase English letters. For each letter in the lowercase English alphabet, find the number of its occurrences from the $l$-th character through the $r$-th character of $f^{10^{100}} (S)$.
Here, $f^{10^{100}} (S)$ is the string $f(f(f( ... f(S) ... )))$ obtained by applying $f$ to $S$ $10^{100}$ times.
Input is given from Standard Input in the following format:
$S$ $l$ $r$
Print $26$ integers in a line with spaces in between. The $i$-th integer should be the number of the occurrences of the $i$-th letter in the lowercase English alphabet from the $l$-th character through the $r$-th character of $f^{10^{100}} (S)$.
abaaba 6 10
3 2 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0
Since $f($abaaba
$)=$abaababaab
, the first ten characters in $f^{10^{100}}(S)$ is also abaababaab
. Thus, the sixth through the tenth characters are abaab
. In this string, a
appears three times, b
appears twice and no other letters appear, and thus the output should be $3$ and $2$ followed by twenty-four $0$s.
