1. Given an array of values to be sorted, set up an auxiliary array of initially empty "pigeonholes", one pigeonhole for each key in the range of the keys in the original array. 2. Going over the original array, put each value into the pigeonhole corresponding to its key, such that ...
TheindexOf()method searches an array for an element value and returns its position. Note:The first item has position 0, the second item has position 1, and so on. Example Search an array for the item "Apple": constfruits = ["Apple","Orange","Apple","Mango"]; ...
