Topic Link: http://acm.hdu.edu.cn/showproblem.php?pid=5478 Title: Find All (=0) that satisfy the modulus equation a^ (k1*n+b1) +b^ (k2*n-k2+1) a,b (mod C) and output in ascending order. Where C is prime and less than 2*10^5,a,b Analysis: Because of the existence of any positive integer n, n=1: a^ (K1+B1) +b=0 (mod c), we multiply both sides of the equation by A^k1
Test instructions Give three dice, the dice have a k1,k2,k3 face. Each time you roll the dice, you get the number of points and steps to move forward, if the result of the dice is c1,c2,c3 (ordered) back to the original point. Start at 0 and reach the point greater than N, then the game is over. The expectation of the number of dice to be thrown. The transfer equation is: Dp[i] = dp[i+l1+l2+l3]* (1/K1/K2/K3
1 Let's think about it in a different place, like the kitchen?"ARM, Samsung, NVIDIA, TSMC, what are the roles of these vendors?" "," Samsung's Orion and Nvidia's Tegra 3 are all known as arm-based cortex-a9, and why do they look completely different from each other and perform differently? "What the hell is arm doing?" What is Samsung doing? What is the relationship and connection between them? ” These questions are believed to have appeared in the m
