There are 3 small problems.
1)Using the functions:
Position, ReplacePart, Take, Drop, Part, Rest, First and Last
I have to get { { 1 } , { 2 , 3 , 4 , 5 , 6 } } out of Range[ 6 ]
2) Using the functions:
Table, Random, Range
I have to get { {0} , { 0 , 2 } , { 0 , 2 , 4 } , { 0 , 2 , 4 , 6 } , { 0 , 2 , 4 , 6 , 8 } } in TWO ways.
---> I found for this second problem:
Table[ 2 * j - 2 , { i , 5 } , { j , i } ]
but another method using the same functions ?
3)using the functions as in problem 1:
Use the lists { a , b , c , d } and { 3 , 2 , 4 , 1 } to create the list { c , b , d , a } in one step.
