Solution Steps

Multiply 4 and 5 to get 20.

$$sort(20+8+10,4+5+8+10+11,12+15+16,18+21+22,19)$$

Add 20 and 8 to get 28.

$$sort(28+10,4+5+8+10+11,12+15+16,18+21+22,19)$$

Add 28 and 10 to get 38.

$$sort(38,4+5+8+10+11,12+15+16,18+21+22,19)$$

Add 4 and 5 to get 9.

$$sort(38,9+8+10+11,12+15+16,18+21+22,19)$$

Add 9 and 8 to get 17.

$$sort(38,17+10+11,12+15+16,18+21+22,19)$$

Add 17 and 10 to get 27.

$$sort(38,27+11,12+15+16,18+21+22,19)$$

Add 27 and 11 to get 38.

$$sort(38,38,12+15+16,18+21+22,19)$$

Add 12 and 15 to get 27.

$$sort(38,38,27+16,18+21+22,19)$$

Add 27 and 16 to get 43.

$$sort(38,38,43,18+21+22,19)$$

Add 18 and 21 to get 39.

$$sort(38,38,43,39+22,19)$$

Add 39 and 22 to get 61.

$$sort(38,38,43,61,19)$$

To sort the list, start from a single element 38.

$$38$$

Insert 38 to the appropriate location in the new list.

$$38,38$$

Insert 43 to the appropriate location in the new list.

$$38,38,43$$

Insert 61 to the appropriate location in the new list.

$$38,38,43,61$$

Insert 19 to the appropriate location in the new list.

$$19,38,38,43,61$$

Evaluate

$$38,\ 38,\ 43,\ 61,\ 19$$
