What is orange?
A function loops through one array and does a binary search on another:
function mysteryFunction(arr1, arr2) {
for (let i = 0; i < arr1.length; i++) {
binarySearch(arr2, arr1[i]); // Assume this is O(log n)
}
}
What is O(n log n)
In a dramatic chase scene, a baby zombie rides a chicken right into the heroes’ base—but it wasn’t random. The zombie had detailed knowledge of the layout, thanks to a targeted deception campaign involving fake server invites.
