Map

A map is defined as the name of a higher-order function in most of the programming languages that applies a given function to each element of a functor, such as a list, and returns a list of results in the same order. A map is also called the collection of values based on a key, i.e. a key and value pair. A map has its own set of keys. Duplicate keys are not permitted in the Map, although duplicate values are permitted. Because a Map cannot be navigated, it must be converted to a Set using the keySet() or entrySet() methods. For key-value association mapping, such as dictionaries, maps are ideal.

Question

Java Foundations Consider the following Java method to reverse an array, i.e. rearrange its elements to the opposite order. An array containing {1, 3, 5} would contain {5, 3, 1} after being reversed. public static void arrayReverse(int[] array) { int le, ri; for (le = 0, ri = array.length - 1; le < array.length / 2; le++, ri--) { int temp = array[le]; array[le] = array[ri]; array[ri] = temp; } } Write the worst-case runtime efficiency of arrayReverse in BigOh notation.
