Now, from the five rules above, we could make the mutiple maximum.

to an N, find the integer k, fits

A=2+3+4+...+(k-1)+k <= N < A+(k+1)=B

Suppose N = A + p, (0 <= p < k+1)

1) p=0, then answer is Set A

2) 1<=p<=k-1 then answer is Set B - { k+1-p }

3) p=k, then answer is Set A - {2} + {k+2}

�?�? 把一整数转换为字�W�串

详细解释:itoa是英文integer to string a(��整形数转化��Z��个字�W�串,�q�将��g��存在a�?
的羃�?其中value��转化的整�? radix是基数的意�?卛_��value转化为几�q�制的数,之后在保存在a �?
作用:实现数制之间的�{�?br>比较:ltoa,其中l是long integer(长整形数)

最��公共子序列

zhongguoa — Tue, 08 Apr 2008 05:27:00 GMT

Longest Common Subsequence

Problem

Given a sequence A = < a1, a2, ..., am >, let sequence B = < b1, b2, ..., bk > be a subsequence of A if there exists a strictly increasing sequence ( i1 is a subsequence of A= < a, b, c, f, d, c > with index sequence < 1, 2, 3 ,5 >.
Given two sequences X and Y, you need to find the length of the longest common subsequence of X and Y.

Input

The input may contain several test cases.

The first line of each test case contains two integers N (the length of X) and M(the length of Y), The second line contains the sequence X, the third line contains the sequence Y, X and Y will be composed only from lowercase letters. (1<=N, M<=100)

Input is terminated by EOF.

Output

Output the length of the longest common subsequence of X and Y on a single line for each test case.

Sample input

6 4 abcfdc abcd 2 2 ab cd

Sample output

4 0 #include <stdio.h> char x[105],y[105]; int c[109][109],i,j,leny,lenx; int main(){ while(scanf("%d %d",&lenx,&leny)!=EOF){ scanf("%s",&x); scanf("%s",&y); for(i=0;i<=leny;i++) c[0][i]=0; for(i=1;i<=lenx;i++) c[i][0]=0; for(i=1;i<=lenx;i++){ for(j=1;j<=leny;j++){ if(x[i-1]==y[j-1]) c[i][j]=c[i-1][j-1]+1; else{ if(c[i-1][j]>=c[i][j-1]) c[i][j]=c[i-1][j]; else c[i][j]=c[i][j-1]; } } } printf("%d\n",c[lenx][leny]); } return 0; }

最大公�U�数函数gcd(int a,int b)的构造和ax=b (mod n) 的解

zhongguoa — Tue, 08 Apr 2008 04:53:00 GMT

Problem

Give you a modular equation ax=b (mod n). Count how many different x (0<=x

Input

The input may contain several test cases.

Each test contains a line with three integers a, b and n, each integer is positive and no more than 10^9.

Input is terminated by EOF.

Output

For each test case, output a line containing the number of solutions.

Sample input

4 2 6

Sample output

2

#include <stdio.h>
long a,b,n;
int gcd(long a,long b){
    if(a==0){
        return b;
    }
    else
    {
        return gcd(b%a,a);
    }
}
int main(){
    while(scanf("%d %d %d",&a,&b,&n)!=EOF){
        long d=gcd(a,n);
        if(b%d==0)
            printf("%d\n",d);
        else printf("0\n",d);
    }
    return 0;
}
