**Example 1:** Write the given set of elements in descending order.

211, 123, 256, 154

**Solution: **

Finding the largest element from the set and writing it.

256

Excluding 256 from the set and finding the largest element to write at the next place.

256, 211

Again excluding 211 from the given set and finding the largest element to fill the next space.

256, 211, 154

Excluding 211, the set has only one element left, that is, 123. Writing it at the next place.

256, 211, 154, 123

Excluding 123, the set becomes empty.

Hence, the elements in descending order will be written as,

256, 211, 154, 123**Example 2:** Find the second smallest element from the given set of numbers.

65, 54, 78, 23, 29

Solution: To find the second smallest number, we can write the elements in the descending order and the second last element in the list will be the second smallest element.

**Step 1:** Write the largest element.

78

**Step 2:** Exclude 78 from the set and the set becomes 65, 54, 23, 29. Write the largest element of this set at the next place.

78, 65

**Step 3:** Exclude 65 from the set and the set becomes 54, 23, 29. Write the largest element of this set at the next place.

78, 65, 54

**Step 4:** Exclude 54 from the set and the set becomes 23, 29. Write the largest number at the next place.

78, 65, 54, 29

**Step 5:** Exclude 29 and the set becomes 23. Write the largest element at the next place.

78, 65, 54, 29, 23

**Step 6:** Exclude 23 and the set becomes empty.

Hence, the given numbers in descending order are:

**78, 65, 54, 29, 23**

The second last element in the list is **29**. It implies that the second smallest element is **29**.
