@目录前言：信号处理前言：继续……信号处理信号是由操作系统传给进程的中断，会提早终止一个程序。头文件中。SIGABRT 程序的异常终止，如调用abort。SIGFPE 错误的算术运算，比如除以零或导致溢出的操作。SIGILL 检测非法指令。SIGINT 程序终止(interrupt)信号。SIGSEGV 非

线段树P4681[THUSC2015]平方运算简要题意给定一个序列，区间.map([](intx){x=x*x%p;});，区间求和。p给定，为小质数。\(N,M\le105\)。题解而把一个数看作一个点，向其平方取模连一条边，则最终必然构成一个基环森林，注意到\(P\)很小，每个数经过至多\(11\)次迭代之后
