HDU5053the Sum of Cube(水题) 题目链接 题目大意:给你L到N的范围,要求你求这个范围内的全部整数的立方和. 解题思路:注意不要用int的数相乘赋值给longlong的数,会溢出. 代码: #include <cstdio> #include <cstring> const int N = 10005; typedef long long ll; ll t[N]; void init () { for (ll i = 1; i <= N - 5; i++…

Description A range is given, the begin and the end are both integers. You should sum the cube of all the integers in the range.   Input The first line of the input is T(1 <= T <= 1000), which stands for the number of test cases you need to solve. E…

http://acm.hdu.edu.cn/showproblem.php?pid=5053 题目大意: 求出A^3+(A+1)^3+(A+2)^3+...+B^3和是多少 解题思路: 设f(n)=1~n的立方和,则A^3+(A+1)^3+(A+2)^3+...+B^3=f(B) - f(A - 1) 题目给的数的范围是1~10000,1~10000立方和不会超过__int64(long long)的范围.由于是10000个数立方和. 所以可以选择打表(不知道立方和的公式,可以选择打表). 立方…
