描述:
两个整数a和b,如果a的不包含自身的因子之和等于b,并且b的不包含自身的因子和等于a,且a不等于b,则称a,b为一对亲密数。
找出满足a<=10000且b<=10000的全部亲密数对。
A pair of close numbers(a and b) is defined as follows: the sum of a’s factors equals b and the sum of b’s factors equals a,but a does not equals b.Find all close numbers which are not greater than 10000.

None
输出:
升序输出所有满足条件的数对,每对数字一行,小数字在前,大数字在后,用空格分隔。注意:本题要求程序效率要高,直接写成二重循环肯定超时。
Output all pair of close numbers in ascending order,and each pair occupies one line with the smaller one in front and the pair is se
