CF1702B.Polycarp Writes a String from Memory
Polycarp Writes a String from Memory
Polycarp has a poor memory. Each day he can remember no more than of different letters.
Polycarp wants to write a non-empty string of consisting of lowercase Latin letters, taking minimum number of days. In how many days will he be able to do it?
Polycarp initially has an empty string and can only add characters to the end of that string.
For example, if Polycarp wants to write the string lollipops, he will do it in days:
- on the first day Polycarp will memorize the letters
l,o,iand writelolli; - On the second day Polycarp will remember the letters
p,o,s, addpopsto the resulting line and get the linelollipops.
If Polycarp wants to write the string stringology, he will do it in days:
- in the first day will be written part
str; - on day two will be written part
ing; - on the third day, part of
ologwill be written; - on the fourth day, part of
ywill be written.
For a given string , print the minimum number of days it will take Polycarp to write it.
Input
The first line of input data contains a single integer () — the number of test cases.
Each test case consists of a non-empty string consisting of lowercase Latin letters (the length of the string does not exceed ) — the string Polycarp wants to construct.
It is guaranteed that the sum of string lengths over all test cases does not exceed .
Output
For each test case, print a single number — minimum number of days it will take Polycarp to write the string from memory.
