Variable Src
Title: Src
Description: The starting arry, indexed by Prev_state.
Definition: Table(Prev_State)(77,44,19,70,76,95,53,20,59,53,99,59,30,87,27,100,3,17,50,11)

Variable Src_re_indexed_to_Ne
Title: Src re-indexed to Next_state
Description: Your task here is to re-index Src from prev_state to Next_state. In this task, both indexes have identical elements.

WindState: 2,413,223,476,224

Index J
Title: J
Definition: 'a'..'t'
NodeLocation: 96,216,1
NodeSize: 48,24

Variable Src_re_indexed_to_J
Title: Src re-indexed to J
Description: In this task, you are to re-index the array Src, indexed by Prev_state, to an array indexed by J. These two indexes have the same length, but different elements. The resulting array should have the same data as the original Src, but be indexed by J.

Variable Src_re_indexed_to_J1
Title: Src re-indexed to J
Description: In this task, you are to re-index the array Src, indexed by Prev_state, to an array indexed by J. These two indexes have the same length, but different elements. The resulting array should have the same data as the original Src, but be indexed by J.
Definition: Src[ @Prev_State = @J ]

Variable The_odd_rows_of_Src1
Title: The odd rows of Src
Description: In this task, you are to extract only the rows named in Odd_states. The result should be indexed only be Odd_states.
