Decimal to Octal Conversion Problem Statement

Convert a given decimal number into its equivalent octal representation.

Explanation:

The octal number system is a base-8 system, meaning each digit ranges from 0 to 7.

Input:

The first line contains a single integer 'T', the number of test cases.
The next 'T' lines each contain an integer 'X', the decimal number to be converted.

Output:

Print the octal value of 'X' for each test case on a new line.

Example:

Input:
3
10
20
65
Output:
12
24
101

Constraints:

• 1 <= T <= 10⁵
• 0 <= X <= 10⁹

Note: The input/output handling is already managed. You need to implement the function logic.
