Fill in missing values based on series and populate second row based on previous or next row in pyspark

问题

I have a csv with 4 columns. The file contains some missing rows based on the series.

Input:-

No  A   B   C
1   10  50  12
3   40  50  12
4   20  60  15
6   80  80  18

Output:-

No  A   B   C
1   10  50  12
2   10  50  12
3   40  50  12
4   20  60  15
5   20  60  15
6   80  80  18

I need pyspark code to generate the above output.
