Problem Description
The counter-terrorists found a time bomb in the dust. But this time the terrorists improve on the time bomb. The number sequence of the time bomb counts from 1 to N. If the current number sequence includes the sub-sequence “49”, the power of the blast would add one point. Now the counter-terrorist knows the number N. They want to know the final points of the power. Can you help them?Input
The first line of input consists of an integer T (1 <= T <= 10000), indicating the number of test cases. For each test case, there will be an integer N (1 <= N <= 2^63-1) as the description.The input terminates by end of file marker.
Output
For each test case, output an integer indicating the final points of the power.Sample Input
3 1 50 500Sample Output
0 1 15这题跟不要62有点区别,最后的状态要判断下,相比之下复杂了点。并且不能直接算出没有49的数,当然也可能是我没想到正确的做法
