Problem Description
N个气球排成一排,从左到右依次编号为1,2,3....N.每次给定2个整数a b(a <= b),lele便为骑上他的“小飞鸽"牌电动车从气球a开始到气球b依次给每个气球涂一次颜色。但是N次以后lele已经忘记了第I个气球已经涂过几次颜色了,你能帮他算出每个气球被涂过几次颜色吗?
 

Input
每个测试实例第一行为一个整数N,(N <= 100000).接下来的N行,每行包括2个整数a b(1 <= a <= b <= N)。 当N = 0,输入结束。
 

Output
每个测试实例输出一行,包括N个整数,第I个数代表第I个气球总共被涂色的次数。
 

Sample Input
3 1 1 2 2 3 3 3 1 1 1 2 1 3 0
 

Sample Output
1 1 1 3 2 1
 答案如下:
#include <stdio.h>
int s[100005];
int main()
{
    int n,i,a,b;
    while(~scanf("%d",&n))
    {
        if(n==0) break;
        for(i=1;i<=n;i++)
            s[i]=0;
        for(i=1;i<=n;i++)
        {
            scanf("%d%d",&a,&b);
            s[a]++;
            s[b+1]--;
        }
        printf("%d",s[1]);
        for(i=2;i<=n;i++)
        {
            s[i]+=s[i-1];
            printf(" %d",s[i]);
        }
        printf("\n");
    }
    return 0;

You can kick me. I am a red basketball. You can throw me.
