Kostya likes the number 4 much. Of course! This number has such a lot of properties, like:
 Four is the smallest composite number;
 It is also the smallest Smith number;
 The smallest noncyclic group has four elements;
 Four is the maximal degree of the equation that can be solved in radicals;
 There is fourcolor theorem that states that any map can be colored in no more than four colors in such a way that no two adjacent regions are colored in the same color;
 Lagrange's foursquare theorem states that every positive integer can be written as the sum of at most four square numbers;
 Four is the maximum number of dimensions of a real division algebra;
 In bases 6 and 12, 4 is a 1automorphic number;
 And there are a lot more cool stuff about this number!
Impressed by the power of this number, Kostya has begun to look for occurrences of four anywhere. He has a list of T integers, for each of them he wants to calculate the number of occurrences of the digit 4 in the decimal representation. He is too busy now, so please help him.
Input
The first line of input consists of a single integer T, denoting the number of integers in Kostya's list.
Then, there are T lines, each of them contain a single integer from the list.
Output
Output T lines. Each of these lines should contain the number of occurences of the digit 4 in the respective integer from Kostya's list.
Constraints
 1 ≤ T ≤ 10^{5}
 (Subtask 1): 0 ≤ Numbers from the list ≤ 9  33 points.
 (Subtask 2): 0 ≤ Numbers from the list ≤ 10^{9}  67 points.
Example
Input: 5 447474 228 6664 40 81 Output: 4 0 1 1 0
