"QAQ" is a word to denote an expression of crying. Imagine "Q" as eyes with tears and "A" as a mouth.

Now Diamond has given Bort a string consisting of only uppercase English letters of length n. There is a great number of "QAQ" in the string (Diamond is so cute!). $8$ illustration by 猫屋 https://twitter.com/nekoyaliu 

Bort wants to know how many subsequences "QAQ" are in the string Diamond has given. Note that the letters "QAQ" don't have to be consecutive, but the order of letters should be exact.


-----Input-----

The only line contains a string of length n (1 ≤ n ≤ 100). It's guaranteed that the string only contains uppercase English letters.


-----Output-----

Print a single integer — the number of subsequences "QAQ" in the string.


-----Examples-----
Input
QAQAQYSYIOIWIN

Output
4

Input
QAQQQZZYNOIWIN

Output
3



-----Note-----

In the first example there are 4 subsequences "QAQ": "QAQAQYSYIOIWIN", "QAQAQYSYIOIWIN", "QAQAQYSYIOIWIN", "QAQAQYSYIOIWIN".

Hooray! Polycarp turned $n$ years old! The Technocup Team sincerely congratulates Polycarp!

Polycarp celebrated all of his $n$ birthdays: from the $1$-th to the $n$-th. At the moment, he is wondering: how many times he turned beautiful number of years?

According to Polycarp, a positive integer is beautiful if it consists of only one digit repeated one or more times. For example, the following numbers are beautiful: $1$, $77$, $777$, $44$ and $999999$. The following numbers are not beautiful: $12$, $11110$, $6969$ and $987654321$.

Of course, Polycarpus uses the decimal numeral system (i.e. radix is 10).

Help Polycarpus to find the number of numbers from $1$ to $n$ (inclusive) that are beautiful.


-----Input-----

The first line contains an integer $t$ ($1 \le t \le 10^4$) — the number of test cases in the input. Then $t$ test cases follow.

Each test case consists of one line, which contains a positive integer $n$ ($1 \le n \le 10^9$) — how many years Polycarp has turned.


-----Output-----

Print $t$ integers — the answers to the given test cases in the order they are written in the test. Each answer is an integer: the number of beautiful years between $1$ and $n$, inclusive.


-----Example-----
Input
6
18
1
9
100500
33
1000000000

Output
10
1
9
45
12
81



-----Note-----

In the first test case of the example beautiful years are $1$, $2$, $3$, $4$, $5$, $6$, $7$, $8$, $9$ and $11$.

Chef has N laddus of K sweetness each. Chef wants to eat all laddus, but Chef is restricted with the given condition that he must not eat two adjacent laddus. Chef starts calculating the maximum sweetness that he will get from the laddus. Find the maximum sweetness that chef gets at the end of all calculations. 

-----Input:-----
- First-line will contain $T$, the number of test cases. Then the test cases follow. 
- Each test case contains a single line of input, two integers $N, K$. 

-----Output:-----
For each test case, output in a single line answer as Maximum sweetness the chef will have.

-----Constraints-----
- $1 \leq T \leq 10^5$
- $1 \leq N \leq 10^5$
- $1 \leq K \leq 10^5$

-----Sample Input:-----

In each contest, all participants had distinct ranks from first through 10^{10^{10}}-th.
The score of a participant is the product of his/her ranks in the two contests.
Process the following Q queries:
 - In the i-th query, you are given two positive integers A_i and B_i. Assuming that Takahashi was ranked A_i-th in the first contest and B_i-th in the second contest, find the maximum possible number of participants whose scores are smaller than Takahashi's.

-----Constraints-----
 - 1 \leq Q \leq 100
 - 1\leq A_i,B_i\leq 10^9(1\leq i\leq Q)
 - All values in input are integers.

-----Input-----
Input is given from Standard Input in the following format:
Q
A_1 B_1
:
A_Q B_Q

-----Output-----
For each query, print the maximum possible number of participants whose scores are smaller than Takahashi's.

-----Sample Input-----
8
1 4
10 5
3 3
4 11
8 9
22 40
8 36
314159265 358979323

-----Sample Output-----

671644785

Let us denote a participant who was ranked x-th in the first contest and y-th in the second contest as (x,y).
In the first query, (2,1) is a possible candidate of a participant whose score is smaller than Takahashi's. There are never two or more participants whose scores are smaller than Takahashi's, so we should print 1.

Hooray! Polycarp turned $n$ years old! The Technocup Team sincerely congratulates Polycarp!

Polycarp celebrated all of his $n$ birthdays: from the $1$-th to the $n$-th. At the moment, he is wondering: how many times he turned beautiful number of years?

According to Polycarp, a positive integer is beautiful if it consists of only one digit repeated one or more times. For example, the following numbers are beautiful: $1$, $77$, $777$, $44$ and $999999$. The following numbers are not beautiful: $12$, $11110$, $6969$ and $987654321$.

Of course, Polycarpus uses the decimal numeral system (i.e. radix is 10).

Help Polycarpus to find the number of numbers from $1$ to $n$ (inclusive) that are beautiful.


-----Input-----

The first line contains an integer $t$ ($1 \le t \le 10^4$) — the number of test cases in the input. Then $t$ test cases follow.

Each test case consists of one line, which contains a positive integer $n$ ($1 \le n \le 10^9$) — how many years Polycarp has turned.


-----Output-----

Print $t$ integers — the answers to the given test cases in the order they are written in the test. Each answer is an integer: the number of beautiful years between $1$ and $n$, inclusive.


-----Example-----
Input
6
18
1
9
100500
33
1000000000

Output
10
1
9
45
12
81



-----Note-----

In the first test case of the example beautiful years are $1$, $2$, $3$, $4$, $5$, $6$, $7$, $8$, $9$ and $11$.

Chef loves lucky numbers. Everybody knows that lucky numbers are positive integers whose decimal representation contains only the lucky digits 4 and 7. For example, numbers 47, 744, 4 are lucky and 5, 17, 467 are not.

Chef has a positive integer N. He can apply any of the following operations as many times as he want in any order:

-  Add 1 to the number N.

-  Take some digit of N and replace it by any non-zero digit.

-  Add any non-zero leading digit to N.

Find the minimum number of operations that is needed for changing N to the lucky number.

-----Input-----
The first line contains a single positive integer T, the number of test cases. T test cases follow. The only line of each test case contains a positive integer N without leading zeros. 

-----Output-----
For each T test cases print one integer, the minimum number of operations that is needed for changing N to the lucky number.

-----Constraints-----

1 ≤ T ≤ 10

1 ≤ N < 10100000

-----Example-----

The chef is having one array of N natural numbers(numbers may be repeated). i.e. All natural numbers must be less than N. Chef wants to rearrange the array and try to place a natural number on its index of the array, i.e array[i]=i. If multiple natural numbers are found for given index place one natural number to its index and ignore others.i.e. arr[i]=i and multiple i found in array ignore all remaining i's If any index in the array is empty place 0 at that place. i.e. if for arr[i], i is not present do arr[i]=0.

-----Input:-----
- First line will contain $T$, number of testcases. Then the testcases follow. 
- Each testcase contains two lines of input.
- First-line has $N$ denoting the size of an array.
- Second-line has $N$ space-separated natural numbers.

-----Output:-----
For each test case, output in a single line with the new rearranged array.

-----Constraints-----
- $1 \leq T \leq 10^3$
- $2 \leq N \leq 10^3$
- $arr[i] \leq N-1$

-----Sample Input:-----
2
2
1 1
4
1 1 2 1

-----Sample Output:-----
0 1
0 1 2 0

-----EXPLANATION:-----
For 1) $1$ occurs twice in the array hence print 0 at 0th index and 1 at 1st index
For 2) $1$ occurs thrice and 2 once in the array hence print 0 at 0th index and 1 at 1st index, 2 at 2nd index and 0 at 3rd index.

You are given an array of N integers a1, a2, ..., aN and an integer K. Find the number of such unordered pairs {i, j} that 

- i ≠ j
- |ai + aj - K| is minimal possible

Output  the minimal possible value of |ai + aj - K| (where i ≠ j) and the number of such pairs for the given array and the integer K.

-----Input-----
The first line of the input contains an integer T denoting the number of test cases. The description of T test cases follows.

The first line of each test case consists of two space separated integers - N and K respectively.

The second line contains N single space separated integers - a1, a2, ..., aN respectively.

-----Output-----
For each test case, output a single line containing two single space separated integers - the minimal possible value of |ai + aj - K| and the number of unordered pairs {i, j} for which this minimal difference is reached.

-----Constraints-----

- 1 ≤ T ≤ 50
- 1 ≤ ai, K ≤ 109
- N = 2 - 31 point.
- 2 ≤ N ≤ 1000 - 69 points.

-----Example-----
Input:
1   
4 9
4 4 2 6

Output:
1 4

-----Explanation:-----
The minimal possible absolute difference of 1 can be obtained by taking the pairs of a1 and a2, a1 and a4, a2 and a4, a3 and a4.

Create a program that will return whether an input value is a str, int, float, or bool. Return the name of the value.

### Examples
- Input = 23 --> Output = int
- Input = 2.3 --> Output = float
- Input = "Hello" --> Output = str
- Input = True --> Output = bool
