Among all the factors of a positive integer N, there may exist several consecutive numbers. For example, 630 can be factored as 3×5×6×7, where 5, 6, and 7 are the three consecutive numbers. Now given ...

让我们定义d​n​​为：d​n​​=p​n+1​​−p​n​​，其中p​i​​是第i个素数。显然有d​1​​=1，且对于n>1有d​n​​是偶数。“素数对猜想”认为“存在无穷多对相邻且差为2的素数”。现给定任意正整数N(<10​5​​)，请计算不超过N的满足猜想的素数对的个数。输入格式:输入在一行给出正整数N。输出格式:在一行中输出不超过N的满足猜想的素数对的个数。...

GivenNrational numbers in the formnumerator/denominator, you are supposed to calculate their sum.本题类似题为B1034/A1088 有理数四则运算：两个分数的加减乘除运算Input Specification:Each input file contains one test ca...

本题要求编写程序，计算 2 个有理数的和、差、积、商。A1081 Rational Sum ：给出多个分数相加输入格式：输入在一行中按照a1/b1 a2/b2的格式给出两个分数形式的有理数，其中分子和分母全是整型范围内的整数，负号只可能出现在分子前，分母不为 0。输出格式：分别在 4 行中按照有理数1 运算符 有理数2 = 结果的格式顺序输出 2 个有理数的和、差、积、...

最大公约数：证明可知：a与b的最大公约数 与 b与 a%b 的最大公约数相同int gcd(int a, int b){ if(b == 0) return a; else return gcd(b, a % b);}最小公倍数：已知a, b 求得的最大公约数为 c, 则最小公倍数为 ab / c分数的四则运算：代码模板：...

A number that will be the same when it is written forwards or backwards is known as aPalindromic Number. For example, 1234321 is a palindromic number. All single digit numbers are palindromic numbers...

Notice that the number 123456789 is a 9-digit number consisting exactly the numbers from 1 to 9, with no duplication. Double it we will obtain 246913578, which happens to be another 9-digit number con...

本题要求计算A/B，其中A是不超过 1000 位的正整数，B是 1 位正整数。你需要输出商数Q和余数R，使得A=B×Q+R成立。输入格式：输入在一行中依次给出A和B，中间以 1 空格分隔。输出格式：在一行中依次输出Q和R，中间以 1 空格分隔。输入样例：123456789050987654321 7输出样例：17636684150...

Given any positive integerN, you are supposed to find all of its prime factors, and write them in the formatN=p​1​​​k​1​​​​×p​2​​​k​2​​​​×⋯×p​m​​​k​m​​​​.Input Specification:Each input file co...

The task of this problem is simple: insert a sequence of distinct positive integers into a hash table, and output the positions of the input numbers. The hash function is defined to beH(key)=key%TSiz...
