Find the number of k-divisible numbers on the segment [a, b]. In other words you need to find the number of such integer values x that a ≤ x ≤ b and x is divisible by k.

The only line contains three space-separated integers k, a and b (1 ≤ k ≤ 1018; - 1018 ≤ a ≤ b ≤ 1018).

	Class: BigInteger
	An arbitrarily-large integer.
	<BigInteger> objects should be considered immutable. None of the "built-in"
	methods modify *this* or their arguments. All properties should be
	considered private.
	All the methods of <BigInteger> instances can be called "statically". The
	static versions are convenient if you don't already have a <BigInteger>
	object.
	As an example, these calls are equivalent.
	> BigInteger(4).multiply(5); // returns BigInteger(20);
	> BigInteger.multiply(4, 5); // returns BigInteger(20);
	> var a = 42;
	> var a = BigInteger.toJSValue("0b101010"); // Not completely useless...

	Constructor: BigInteger()
	Convert a value to a <BigInteger>.
	Although <BigInteger()> is the constructor for <BigInteger> objects, it is
	best not to call it as a constructor. If *n* is a <BigInteger> object, it is
	simply returned as-is. Otherwise, <BigInteger()> is equivalent to <parse>
	without a radix argument.
	> var n0 = BigInteger();      // Same as <BigInteger.ZERO>
	> var n1 = BigInteger("123"); // Create a new <BigInteger> with value 123
	> var n2 = BigInteger(123);   // Create a new <BigInteger> with value 123
	> var n3 = BigInteger(n2);    // Return n2, unchanged
	The constructor form only takes an array and a sign. *n* must be an
	array of numbers in little-endian order, where each digit is between 0
	and BigInteger.base.  The second parameter sets the sign: -1 for
	negative, +1 for positive, or 0 for zero. The array is *not copied and
	may be modified*. If the array contains only zeros, the sign parameter
	is ignored and is forced to zero.
	> new BigInteger([5], -1): create a new BigInteger with value -5

	If no base is provided, or *base* is 10, the number can be in exponential

	If any characters fall outside the range defined by the radix, an exception

Mishka wants to buy some food in the nearby shop. Initially, he has $$$s$$$ burles on his card. Mishka can perform the following operation any number of times (possibly, zero): choose some positive integer number $$$1 \le x \le s$$$, buy food that costs exactly $$$x$$$ burles and obtain $$$\lfloor\frac{x}{10}\rfloor$$$ burles as a cashback (in other words, Mishka spends $$$x$$$ burles and obtains $$$\lfloor\frac{x}{10}\rfloor$$$ back). The operation $$$\lfloor\frac{a}{b}\rfloor$$$ means $$$a$$$ divided by $$$b$$$ rounded down.It is guaranteed that you can always buy some food that costs $$$x$$$ for any possible value of $$$x$$$.Your task is to say the maximum number of burles Mishka can spend if he buys food optimally.For example, if Mishka has $$$s=19$$$ burles then the maximum number of burles he can spend is $$$21$$$. Firstly, he can spend $$$x=10$$$ burles, obtain $$$1$$$ burle as a cashback. Now he has $$$s=10$$$ burles, so can spend $$$x=10$$$ burles, obtain $$$1$$$ burle as a cashback and spend it too.You have to answer $$$t$$$ independent test cases.

The first line of the input contains one integer $$$t$$$ ($$$1 \le t \le 10^4$$$) — the number of test cases. The next $$$t$$$ lines describe test cases. Each test case is given on a separate line and consists of one integer $$$s$$$ ($$$1 \le s \le 10^9$$$) — the number of burles Mishka initially has.

For each test case print the answer on it — the maximum number of burles Mishka can spend if he buys food optimally.

A string $$$a=a_1a_2\dots a_n$$$ is called even if it consists of a concatenation (joining) of strings of length $$$2$$$ consisting of the same characters. In other words, a string $$$a$$$ is even if two conditions are satisfied at the same time:  its length $$$n$$$ is even;  for all odd $$$i$$$ ($$$1 \le i \le n - 1$$$), $$$a_i = a_{i+1}$$$ is satisfied. For example, the following strings are even: "" (empty string), "tt", "aabb", "oooo", and "ttrrrroouuuuuuuukk". The following strings are not even: "aaa", "abab" and "abba".Given a string $$$s$$$ consisting of lowercase Latin letters. Find the minimum number of characters to remove from the string $$$s$$$ to make it even. The deleted characters do not have to be consecutive.

The first line of input data contains an integer $$$t$$$ ($$$1 \le t \le 10^4$$$) —the number of test cases in the test. The descriptions of the test cases follow. Each test case consists of one string $$$s$$$ ($$$1 \le |s| \le 2 \cdot 10^5$$$), where $$$|s|$$$ — the length of the string $$$s$$$. The string consists of lowercase Latin letters. It is guaranteed that the sum of $$$|s|$$$ on all test cases does not exceed $$$2 \cdot 10^5$$$.

For each test case, print a single number — the minimum number of characters that must be removed to make $$$s$$$ even.

6

aabbdabdccc

zyx

aaababbb

aabbcc

oaoaaaoo

bmefbmuyw

NoteIn the first test case you can remove the characters with indices $$$6$$$, $$$7$$$, and $$$9$$$ to get an even string "aabbddcc".In the second test case, each character occurs exactly once, so in order to get an even string, you must remove all characters from the string.In the third test case, you can get an even string "aaaabb" by removing, for example, $$$4$$$-th and $$$6$$$-th characters, or a string "aabbbb" by removing the $$$5$$$-th character and any of the first three.
