There where few columns in the question.
The columns such as items or products with rows px1,px2...
some 2 columns,
Time period,
and levels..
Levels were 1,2,2,3,4,3,4,4.
The questions was to find the maximum time period and then
calculate the fetched time period with the matching PX column....
Also write the algorithm /method /procedure to traverse from level 4 to
level 1.
I din't understand the algorithm part.
I came across such question for the 1st time.
If any one of you have ever come across similar question then please guide me .
Thank you.
