Question: How to count the maximum and minimum range of non-zeros elements?

let's suppose we have A of length 50 rows how we can calculate the maximum range of non-zeros element and as well as minimum A = [0 0 1 1 1 1 0 0 0 0 0 1 1 0 0 0 0 0 0 0 0 0 1 1 1 0 0 0 0 0 0 0 1 1 0 0 0 0 0 0 0 1 1 1 1 1 0 0 0 0 ] In this case Max and Min should be, Max = 5 Min = 2   Is there a straightforward solution to do this? without using complex looping because in my case data is too large approximately length of A is 220079705, your kind consideration will be highly regarded by all means,

A = [0 0 1 1 1 1 0 0 0 0 0 1 1 0 0 0 0 0 0 0 0 0 1 1 1 0 0 0 0 0 0 0 1 1 0 0 0 0 0 0 0 1 1 1 1 1 0 0 0 0 ]
props = regionprops(logical(A), 'Area');
allLengths = [props.Area];
minLength = min(allLengths)
maxLength = max(allLengths)
