2020年12月13日 · 本文解析了在编程竞赛中使用10^9+7作为模的原因,包括防止整数溢出、为何选择质数作为模,以及如何正确地在计算过程中应用模运算。 在大多数编程比赛中,我们都需要以10 ^ 9 + 7模为模来回答结果。 这背后的原因是,如果问题约束是大整数,则只有高效的算法才能在允许的有限时间内解决它们。 对两个操作数进行除法运算后得到的余数称为模运算。 进行模运算的 运算符 为’%’。 例如:a%b = c,这意味着,当a除以b时,它将得到余数c,7%2 = …

模7数列求值-CSDN博客
2010年1月2日 · 我们知道斐波那契数列的递推公式为f(n)=f(n-1)+f(n-2) n>=2 f(0)=0 f(1)=1;还有另一种斐波那契数:F(0)=7,F(1)=11,F(n)=F(n-1)+F(n-2)(n>=2)。对于每组输入数据,输出一行,是一个最小的整数m,使得f(n)%P=f(n+m)%P对每一个n成立。
Modulo 10^9+7 (1000000007) - GeeksforGeeks
2022年11月28日 · 10^9+7 fulfills both the criteria. It is the first 10-digit prime number and fits in int data type as well. In fact, any prime number less than 2^30 will be fine in order to prevent possible overflows. How modulo is used: A few distributive properties of modulo are as follows: ( a + b) % c = ( ( a % c ) + ( b % c ) ) % c
Typical hours/shifts in a hospital? : r/medlabprofessionals - Reddit
What do typical hours/shifts look like at a hospital? Are they like nurses and have rotating schedules or does anyone have a consistent M-F 9-5 job here? Update: I'm very happy to see a more stable and traditional schedule here! Thanks guys!
Those with a M-F 9-5 job, do you work over the weekends and why?
M-F 9-5 is already too much imo. A job should only be a tool to have the means to live the rest of your life how you want. So go live your life and don’t feel bad when other people give up theirs for a job
