Explanation / Answer

Answer:

1) [0, 10, 20, 10]

Explanation: We start with index 1 and see 10 >= 20 NO
We increment index from 1 to 3 and see 10>=5 , YES
so WE REMOVE 5 AND ADD 0 at index 0. Hence we get the list as 0, 10, 20 , 10 as 5 is removed

2) [0, 0, 8, 9, -1, 55]

Explanation: We start with index 1 and see 8 >= 2 Yes, we remove 2..
We increment index from 1 to 3 and see 9>=7 , YES, we remove 7
Hence we get 0, 0, 8, 9, -1, 55

3) [0, 0, 0, 0, 16, 9, 64, 25, 0]

Explanation: We start with index 1 and see 0 >= 16, NO
We increment index from 1 to 3 and see 9>=1 , YES, we remove 1
This way we continue at index 5, 7 etc
Hence we get  [0, 0, 0, 0, 16, 9, 64, 25, 0]
