/*
first we can find a[0] and a[n-1] using the range 0,1e18+1 because a[0]>0 && a[n-1]<1e18+1
then using that we can find a[1] by using a[0] because we know that a[1]>=a[0]+1 same for a[n-2]<=a[n-1]-1
so can use MinMax once so that a[0] and a[n-1] is defined, then we can move into the middle so that we can recold {a[1],a[n-2]},{a[2],a[n-3]},....
this solution will be n/2
