1024 raised to power 202 modulo 2011
512 raised to power 225 modulo 2027
另外一个：
You are given a sequence of n numbers from {0,...,p-1}. Can you insert
operators + and * between the numbers that the expression evaluates to 0
modulo p? We use the usual convention for evaluating expressions: * has
precedence over + (thus for example 1+2*3 evaluates to 7). Describe an O(np2
) algorithm for the problem (assume, for simplicity, that arithmetic
operations on numbers from {0,...,p-1}take O(1) time).
多谢各位，能提点一下就很感谢了，书都看了，联系不上去。
