An algorithm is represented in the pseudocode below:

1  nums[0] ← 15
2  nums[1] ← 42
3  nums[2] ← 8
4  nums[3] ← 23
5  FOR x ← 0 TO 2
6      FOR y ← 0 TO 2
7          IF nums[y + 1] < nums[y] THEN
8              temp ← nums[y]
9              nums[y] ← nums[y + 1]
10             nums[y + 1] ← temp
11         ENDIF
12     ENDFOR
13 ENDFOR
