Problem types

Your computer science teacher has kindly requested that you write a program to convert a number, inputted in decimal, to binary to help in teaching students about binary. Also to aid in human processing of numbers, you should group every four bits and separate the groups by space.

Input Specification

The first line will be integer (), the number of numbers to convert to binary. The next lines will be such that ().

Output Specification

For every integer , output the binary representation, grouped into four bit groups, separated by spaces. If necessary, you must pad the first group to have exactly four bits.

Sample Input

3
1
10
255

Sample Output

0001
1010
1111 1111

im new too python may anyone please tell me how to figure out these problems i am confused on what he is sasking me to do. What does this mean? > N N ( 1 ≤ N ≤ 20 1 \le N \le 20 ). and this? > The next N N lines will be i i such that ( i ∈ Z , 0 ≤ i ≤ 10 9 i \in \mathbb{Z}, 0 \le i \le 10^9 ).I would be very grateful if you could help me.

Hint

Java has a method you can call against the Integer class: Integer.toBinaryString(number);

output must be a group with four digits

Note the output specification: (1) 16 --> 10000,output should be:
0001 0000,output should not be:1000 0 (2) 0 --> 0000,1 --> 0001, 7 --> 0111
