Package for this problem was not updated by the problem writer or Codeforces administration after we’ve upgraded the judging servers. To adjust the time limit constraint, solution execution time will be multiplied by 2. For example, if your solution works for 400 ms on judging servers, then value 800 ms will be displayed and used to determine the verdict.

standard outputLittle Petya loves looking for numbers' divisors. One day Petya came across the following problem:

You are given *n* queries in the form "*x*_{i} *y*_{i}". For each query Petya should count how many divisors of number *x*_{i} divide none of the numbers *x*_{i - yi}, *x*_{i - yi + 1}, ..., *x*_{i - 1}. Help him.

Input

The first line contains an integer *n* (1 ≤ *n* ≤ 10^{5}). Each of the following *n* lines contain two space-separated integers *x*_{i} and *y*_{i} (1 ≤ *x*_{i} ≤ 10^{5}, 0 ≤ *y*_{i} ≤ *i* - 1, where *i* is the query's ordinal number; the numeration starts with 1).

If *y*_{i} = 0 for the query, then the answer to the query will be the number of divisors of the number *x*_{i}. In this case you do not need to take the previous numbers *x* into consideration.

Output

For each query print the answer on a single line: the number of positive integers *k* such that
