You are given an array which is initially empty. You need to perform $n$ operations of the given format:

翻译中…
  • "$a$ $l$ $r$ $k$": append $a$ to the end of the array. After that count the number of integer pairs $x, y$ such that $l \leq x \leq y \leq r$ and $\operatorname{mex}(a_{x}, a_{x+1}, \ldots, a_{y}) = k$.
翻译中…

The elements of the array are numerated from $1$ in the order they are added to the array.

To make this problem more tricky we don't say your real parameters of the queries. Instead your are given $a'$, $l'$, $r'$, $k'$. To get $a$, $l$, $r$, $k$ on the $i$-th operation you need to perform the following:

翻译中…
  • $a := (a' + lans) \bmod(n + 1)$,
  • $l := (l' + lans) \bmod{i} + 1$,
  • $r := (r' + lans) \bmod{i} + 1$,
  • if $l \gt r$ swap $l$ and $r$,
  • $k := (k' + lans) \bmod(n + 1)$,

where $lans$ is the answer to the previous operation, initially $lans$ is equal to zero. $i$ is the id of the operation, operations are numbered from $1$.

The $\operatorname{mex}(S)$, where $S$ is a multiset of non-negative integers, is the smallest non-negative integer which does not appear in the set. For example, $\operatorname{mex}(\{2, 2, 3\}) = 0$ and $\operatorname{mex} (\{0, 1, 4, 1, 6\}) = 2$.

Input

翻译中…

The first line contains a single integer $n$ ($1 \leq n \leq 2 \cdot 10^5$) — the length of the array.

翻译中…

The next $n$ lines contain the description of queries.

翻译中…

Each of them $n$ lines contains four non-negative integers $a'$, $l'$, $r'$, $k'$ ($0, \leq a', l', r', k' \leq 10^9$), describing one operation.

Output

翻译中…

For each query print a single integer — the answer to this query.

For the first example the decoded values of $a$, $l$, $r$, $k$ are the following:

翻译中…

$a_1=0,l_1=1,r_1=1,k_1=1$

翻译中…

$a_2=1,l_2=1,r_2=2,k_2=0$

翻译中…

$a_3=0,l_3=1,r_3=3,k_3=1$

翻译中…

$a_4=1,l_4=1,r_4=4,k_4=2$

翻译中…

$a_5=2,l_5=1,r_5=5,k_5=3$

翻译中…

For the second example the decoded values of $a$, $l$, $r$, $k$ are the following:

翻译中…

$a_1=2,l_1=1,r_1=1,k_1=2$

翻译中…

$a_2=2,l_2=1,r_2=2,k_2=1$

翻译中…

$a_3=0,l_3=1,r_3=3,k_3=0$

翻译中…

$a_4=0,l_4=2,r_4=2,k_4=3$

翻译中…

$a_5=0,l_5=3,r_5=4,k_5=0$
