#7085. 神秘嘅三元組序列

Statistics

Jeffery 發現咗一個好神奇嘅三元組序列 $\{(a_k,b_k,c_k)\}_{k=0}^{\infty}$:

  • $(a_0,b_0,c_0)=(2,1,0)$;而且

  • 對每個非負整數 $k$,$(a_{k+1},b_{k+1},c_{k+1})=(a_k^2+b_k^2,a_kb_k+b_kc_k,b_k^2+c_k^2)$。

例如,$(a_1,b_1,c_1)=(5,2,1)$,而 $(a_2,b_2,c_2)=(29,12,5)$。

如果考慮呢個序列對整數 $p$ 取模之後嘅結果,有啲三元組永遠都唔會喺呢個序列出現,有啲會週期性噉出現,其他三元組就只會出現一次。

Jeffery 想知道你可唔可以幫佢搵出,由指定位置開始,一啲三元組第一次出現嘅位置。你可唔可以幫下佢?

輸入格式

第一行有兩個整數 $n$ 同 $p$($1 \le n \le 5000$,$1 \le p \le 2^{30}$),其中 $n$ 表示問題數目,$p$ 表示下面所有問題都喺模 $p$ 嘅意義下考慮。

跟住嘅 $n$ 行,每行有四個整數 $x$、$y$、$z$ 同 $m$($0 \le x,y,z < p$,$0 \le m \le 10^{18}$),表示一個問題,要求你搵出滿足 $k \ge m$ 同 $(a_k,b_k,c_k)\equiv(x,y,z)\pmod p$ 嘅最細整數 $k$。

輸出格式

對每個問題,喺獨立一行輸出一個整數,表示嗰個問題嘅答案。如果冇呢個整數 $k$,就輸出 $-1$。

說明

喺第一個樣例入面,$(a_0,b_0,c_0)\equiv(2,1,0)$、$(a_1,b_1,c_1)\equiv(5,2,1)$、$(a_2,b_2,c_2)\equiv(7,1,5)$、$(a_{2T+3},b_{2T+3},c_{2T+3})\equiv(6,1,4)$、$(a_{2T+4},b_{2T+4},c_{2T+4})\equiv(4,10,6)\pmod{11}$,當中 $T=0,1,2,\ldots$

喺第二個樣例入面,$(a_0,b_0,c_0)\equiv(2,1,0)$、$(a_1,b_1,c_1)\equiv(5,2,1)$、$(a_{2T+2},b_{2T+2},c_{2T+2})\equiv(9,2,5)$、$(a_{2T+3},b_{2T+3},c_{2T+3})\equiv(5,8,9)\pmod{10}$,當中 $T=0,1,2,\ldots$
