for example - array is 4,2,5,6,1

Answer 1

Use a for-loop to iterate over all of your values, and in that for-loop, use a sin() function. If you want the function to be from 0 to 6, and all integers, then it'll look like round((1 + sin(x)) * 3). Firstly, the numbers (which are originally -1 to 1) are made positive by adding one (they are now 0 to 2) and then expanded to 0 to 6 by being multiplied. Since they need to be integers, they are rounded.
