// level is found. Repeat all this for the next item until proper count of items
// is reached.
// 2) Get all items that have the correct itemId, sort them once based on
// enchantment level,
// and get the range of items that is necessary.
// Method 1 is faster for a small number of items to be exchanged.
// Method 2 is faster for large amounts.
//
// EXPLANATION:
// Worst case scenario for algorithm 1 will make it run in a number of cycles
// given by:
// m*(2n-m+1)/2 where m is the number of items to be exchanged and n is the total
// number of inventory items that have a matching id.
// With algorithm 2 (sort), sorting takes n*log(n) time and the choice is done in
// a single cycle
// for case b (just grab the m first items) or in linear time for case a (find the
// beginning of items
// with correct enchantment, index x, and take all items from x to x+m).
// Basically, whenever m > log(n) we have: m*(2n-m+1)/2 = (2nm-m*m+m)/2 >
// (2nlogn-logn*logn+logn)/2 = nlog(n) - log(n*n) + log(n) = nlog(n) + log(n/n*n)
// =
// nlog(n) + log(1/n) = nlog(n) - log(n) = (n-1)log(n)
// So for m < log(n) then m*(2n-m+1)/2 > (n-1)log(n) and m*(2n-m+1)/2 > nlog(n)
//
// IDEALLY:
// In order to best optimize the performance, choose which algorithm to run, based
// on whether 2^m > n
// if ( (2<<(e.getItemCount()// _amount)) < inventoryContents.length )
// // do Algorithm 1, no sorting
// else
// // do Algorithm 2, sorting
//
// CURRENT IMPLEMENTATION:
// In general, it is going to be very rare for a person to do a massive exchange
// of non-stackable items
// For this reason, we assume that algorithm 1 will always suffice and we keep
// things simple.
// If, in the future, it becomes necessary that we optimize, the above discussion
// should make it clear
// what optimization exactly is necessary (based on the comments under "IDEALLY").
//
