题目连接:10706 - Number Sequence 题目大意:有一个有0 ~ 9组成的序列,1   1 2    1 2 3   1 2 3 4   1 2 3 4 5 ....就是第一位为1. 第二为为1 ,第三为为2, 然后10 的部分注意下, 为1  和0 两个, 100 就是1 , 0和0 三位,以此类推, 要求给出tmp, 输出序列中的tmp位为什么数字. 解题思路:数据很大,肯定不能模拟,找规律. 这两个是为推出来的用来打表的公式: 1.sum[i] = sum[i - 1]…

Valera is a coder. Recently he wrote a funny program. The pseudo code for this program is given below: //input: integers x, k, pa = x;for(step = 1; step <= k; step = step + 1){ rnd = [random integer from 1 to 100]; if(rnd <= p) a = a * 2; else a = a…
