Module convert 

Helper functions to convert between vanilla array and variants.

This is the module-level documentation.

Functions

d1z_to_vanilla

Reverse the delta and zigzag transformation (vanilla_to_d1z).

d1z_to_vanilla_self

Same as d1z_to_vanilla() but modify the original array.

m1_to_vanilla

Add 1 to each value.

m1_to_vanilla_self

Same as m1_to_vanilla() but modify the original array.

vanilla_to_d1z

Transforms the original input into the difference between consecutive values, then zigzag it. If $x > 0$, $zigzag(x) = 2x$, while $x < 0$, $zigzag(x) = -2x - 1$.

vanilla_to_d1z_self

Same as vanilla_to_d1z() but modify the original array.

vanilla_to_m1

Substract 1 from each value.

vanilla_to_m1_self

Same as vanilla_to_m1() but modify the original array.
