HDU2136_Largest prime factor【水题】【筛法求素数】
题目大意:每个素数在素数表中都有一个序号,设1的序号为0,则2 的序号为1,3的序号为2,5的序号为3,以此类推。现在要求输出所 给定的数n的最大质因子的序号,0<n<1000000。 思路:巧用素数打表法。用sum计算素数的序号,将素数连同他的倍 数一起置为它的素数序号,从小到大循环,这样数组里存放的序号就 是最大素数因子的序号了。 注意:初始化时令所有数为0,Prime[0] = Prime[1] = 1。 即Prime[i]为0是素数,Prime[i]为1为素数。改变之后Prime[i]为数i 的最大...
