1. The problem is to arrange a given set of numbers in ascending order. 2. Ascending order means arranging numbers from the smallest to the largest. 3. To do this, compare each number with the others and place them starting from the smallest. 4. For example, if the numbers are $5, 2, 9, 1$, the ascending order is $1, 2, 5, 9$. 5. This method applies to any set of numbers you want to sort in ascending order. 6. If you provide the specific numbers, I can arrange them for you.
