在jxzz上发现的一个做题网站,每周都有训练题,题目质量……前三题比较水,后面好神啊,而且类型差不多,这周似乎是计数专题…… Army Game 然后给出n*m,问需要多少个小红点能全部占领 解法:乘法... Best Divisor 给一个数,问一个数的约数中数字和最大的约数. 解法:直接分解质因数就可以啦. Twins 孪生质数定义为两个质数之差为2,问n,m之间有多少个孪生质数(n<=m<=10^9,m-n<=10^6) 解法:显然直接判断区间内相邻的两个奇数是否为质数就可以啦.然…
Problem: The gray code is a binary numeral system where two successive values differ in only one bit. Given a non-negative integer n representing the total number of bits in the code, print the sequence of gray code. A gray code sequence must begin w…
题目链接:Running Time of Quicksort Challenge In practice, how much faster is Quicksort (in-place) than Insertion Sort? Compare the running time of the two algorithms by counting how many swaps or shifts each one takes to sort an array, and output the dif…
