Even-sum

Subject description:

Has a length of n- (n-<= 100) the number of columns, is defined as the number of columns from 2 starts incrementing the even ordered , asks you to obtain a mean value according to the number per m order, if the last number is less than m, places The actual number averaged. The average output programmed sequence.

Input

A plurality of input data sets, each representing one line, comprising two positive integers n and m, n and m are the meanings described above.

Output

For each set of input data, it outputs a mean value sequence, each output per line.

Sample Input

3 2 
4 2

Sample Output

3 6 
3 7

By the answer:

#include <stdio.h>

int main(){
	int n,m;
	while(scanf("%d %d",&n,&m)!=EOF){
		for(int i=1;i<=n;){
			int sum=0,count=0;
			for(int j=1;j<=m&&i<=n;j++){	
				sum+=2*i;
				count++;       //统计个数
				i++;
			}
			printf("%d",sum/count);
			if(i<=n){
				printf(" ");      //平均值之间需要空格隔开
			}
		}
		printf("\n");       //换行一定要！
    }
    return 0;
}
