A divisor of a positive integer $$$n$$$ is an integer $$$d$$$ where $$$m=\frac{n}{d}$$$ is an integer. In this problem, we define the aliquot sum $$$s(n)$$$ of a positive integer $$$n$$$ as the sum of all divisors of $$$n$$$ other than $$$n$$$ itself. For examples, $$$s(12)=1+2+3+4+6=16$$$, $$$s(21)=1+3+7=11$$$, and $$$s(28)=1+2+4+7+14=28$$$.
With the aliquot sum, we can classify positive integers into three types: abundant numbers, deficient numbers, and perfect numbers. The rules are as follows.
You are given a list of positive integers. Please write a program to classify them.
The first line of the input contains one positive integer $$$T$$$ indicating the number of test cases. The second line of the input contains $$$T$$$ space-separated positive integers $$$n_1,\dots,n_T$$$.
Output $$$T$$$ lines. If $$$n_i$$$ is an abundant number, then print abundant on the $$$i$$$-th line. If $$$n_i$$$ is a deficient number, then print deficient on the $$$i$$$-th line. If $$$n_i$$$ is a perfect number, then print perfect on the $$$i$$$-th line.
