Solve {l}{1}{2}{2}{27}{27}{28}{20}

$$\left. \begin{array} { l } { 1 } \\ { 2 } \\ { 2 } \\ { 27 } \\ { 27 } \\ { 28 } \\ { 20 } \end{array} \right.$$

Sort

$$1,2,2,20,27,27,28$$

Solution Steps

To sort the list, start from a single element 1.

$$1$$

Insert 2 to the appropriate location in the new list.

$$1,2$$

Insert 2 to the appropriate location in the new list.

$$1,2,2$$

Insert 27 to the appropriate location in the new list.

$$1,2,2,27$$

Insert 27 to the appropriate location in the new list.

$$1,2,2,27,27$$

Insert 28 to the appropriate location in the new list.

$$1,2,2,27,27,28$$

Insert 20 to the appropriate location in the new list.

$$1,2,2,20,27,27,28$$

Evaluate

$$1,\ 2,\ 2,\ 27,\ 27,\ 28,\ 20$$
