Let XYZ is a program which takes integer input from command line.
Below is the list of oparation that needs to be achived:
- A list must be generated with the
input
number of elements in the list starting from one i.e when input is 3List(1,2,3)
must be generated. - Each number in the List generated i.e
numberList = List(1,2,3)
must be used to create seperate lists with elements equal to the number starting from 1, i.e when input is 3;List(1), List(1, 2), List(1,2,3)
must be created and joined together to give outputresultList
asList(1, 1, 2, 1, 2, 3)
.
So how can I achive this using FlatMap??
