WebIf the array is sorted, you can use a binary search instead. This will be much more efficient, since binary search runs in worst-case logarithmic time, making O(log n) comparisons, where n is the size of the slice.. There are the three custom binary search functions: sort.SearchInts, sort.SearchStrings or sort.SearchFloat64s. They all have the signature
