Hi,
I have written an algorithm which iteratively solves the problem. The first iteration consists of 6 steps and all the following iterations consist of 5 steps (first step is skipped).
What I want to calculate is the current (local) step in the iteration from current global step.
For example if there are 41 steps in total which means there are 8 iterations: indices from 1 to 6 belong to 1st iteration indices from 7 to 11 belong to second iteration ...
For calculating the current iteration I have written the following code:
if(currentStep <= 6)
iteration = 1;
else
iteration = floor((currentStep - 7)/5) + 2;
end
The problem remains in calculating local steps. in first iteration the performed steps are: 1, 2, 3, 4, 5, 6 in all the following iterations the performing steps are 2, 3, 4, 5, 6
So what has to be done is to transform the array of global steps
[1 2 3 4 5 6 7 8 9 10 11 12 13 ... 41]
into array of local steps
[1 2 3 4 5 6 2 3 4 5 6 2 3 ... 6]
.
I would appreciate if anyone could help in finding the solution to a given problem.
Thank you!
