Shifting digits of a number is nothing but the exchanging the digits to another place.
Take a number \(358\).
The condition here is to exchange its hundreds and unit digit and form the new number.
That is, exchange \(3\) to \(8\) and \(8\) to \(3\).
Here comes a question.
Which is greater and which is least among the numbers?
To find that express the numbers formed in both ascending and descending order.
The number before shifting is \(358\). Exchanging the hundreds and the units digits, the number after shifting is \(853\).
That is, if we exchange the hundreds and unit digit, the resultant number becomes greater.
