Also pls explain meaning of this question if possible

Technically, it is 0123 if you permit a leading 0. And the question did not specifically rule out a leading 0.
Otherwise, 1023 would be correct

Using the given numbers, the greatest 4-digit number is 4,321 and the smallest 4-digit number is 1,234.
Explanation:
Numbers are categorized according to the number of digits that they have and the place value of a number helps in understanding the value of each digit. The 4 digit number series begins with the number 1,000 and ends with the number 9,999. 4-digit numbers are the numbers having 4-digits and we can form 4-digit numbers by using any digits from 0-9, but the number should begin with digit 1 or a number greater than 1.
How to Write Numbers up to 4-Digits?
4-digit numbers are written or read according to the place values of the digits. In 4 digit numbers, the four digits correspond to the four place values- ones, tens, hundreds and thousands. When a number is written in standard form, each group of digits is separated by a comma which forms a period. The first period which is known as the 'ones period' is formed with the first three digits of the number. It should be noted that the placement of commas starts with 4 digit numbers. We put a comma after the hundreds place from the right because the first-period (ones) ends and the second period of thousands begins. For example, 3210 is a 4-digit number and after placing the comma, it is written as 3,210.
The smallest 4-digit number is 1,000 and the largest 4-digit number is 9,999, and there are a total of 9000 numbers from 1000 to 9999. We can make many four-digit numbers by using digits from 0 to 9 but we need to remember that the thousands place in a 4-digit number should not be 0. For example, 0875 is not a four-digit number, the number is considered as a three-digit number, that is, 875.
4-digit numbers can be written in three forms, i.e., in the numeral form, in words, and in the expanded form. For example, 2345 is a 4-digit number. In the numeral form, it is written as 2,345. In words, it is written as: Two thousand three hundred forty-five. In the expanded form it is written as: 2000 + 300 + 40 + 5, or, 2 thousands + 3 hundreds + 4 tens + 5 ones.
How To Decompose Numbers up to 4-Digits?
As already discussed above, a 4 digit number has the following place values – Thousands, Hundreds, Tens and Ones. To decompose 4-digit numbers we multiply each digit of the 4-digit number with its value, that is, 1000, 100, 10, and 1 respectively. For example, the given 4-digit number 5627 can be decomposed as follows:
5 is at thousands place and its place value is 5 × 1000 = 5000
6 is at hundreds place and its place value is 6 × 100 = 600
2 is at tens place and its place value is 2 × 10 = 20
7 is at ones place and its place value is 7 × 1 = 7
So, the expanded form of 5627 = 5000 + 600 + 20 + 7
Observe the following figure which shows how to write a 4-digit number according to its place values. In this case, we have taken the example of a 4-digit number: 4,123. Here, 4 is written at the thousands place, 1 is written at the hundreds place, 2 is written at the tens place and 3 is written at ones place.
