the first problem is 112.It's a complicated problem but not hard.We can deal with the input firstly,put all the valid character into a string and we can use a var "pair" substitute the
題目類型:數學,數論心得:找規律,打表代碼:#include#include#includeint main(){ long n,row,column;while(scanf("%d",&n)==1){row=column=0;if(n==0)break;long k=0;k=(long)(sqrt(n)+0.5);if(k*k>n)k=k-1;if(k*k==n){if(k%2){row=1;column=k;}else
問題描述:計算一次加法的代價為兩個加數的和,求計算一條加法公式的總代價類型:哈弗曼演算法解法:用兩個隊列類比哈弗曼即可,或者優先隊列?#include<cstdio>#include<cstdlib>#include<string>#include<algorithm>using namespace std;const int MAXSIZE=500001; long long P[MAXSIZE],Q[MAXSIZE]; int
I just simulate the flipping. We are not required to find the optimal solution, so I choose a way easy to understand. I find the biggest cake in the unsorted stack, and then check its position. If it is at the bottom of the stack, then nothing need
At the first look, this problem seems to be tricky to solve. However, if you implement all the specifications precisely, it would be already solved. There's no need to "translate" the problem's specifications.Code:/***********************************
問題描述:幾個人的01背包問題問題解法:看看147那道,就知道一樣的#include<cstdio>#include<cstdlib>#include<string>using namespace std;const int maxp=105*1000;const int maxn=1001;int v[105];long long d[maxp];int p[maxn],w[maxn];int main(){ int S,n; int
