the if block will never occur because you sort your digits but then you compare it to the "check" array which has 0 at the end of the array and not the start.
if you look up the (connect the ropes to minimise cost) it is much better explained there and will remove confusion because many people think for numbers [1,2,3,4,5] the minimal cost is 34 but it is actually 33'
