Question

In JAVA, Given an array of strings, return a new array containing the first N strings. N will be in the range 1..length.

wordsFront(["a", "b", "c", "d"], 1) → ["a"]
wordsFront(["a", "b", "c", "d"], 2) → ["a", "b"]
wordsFront(["a", "b", "c", "d"], 3) → ["a", "b", "c"]

Answer 1

public String[] wordsFront(String arr[], int n){
  String result[] = new String[n];
  for(int i = 0;i<n && i<arr.length;i++){
    result[i] = arr[i];
  }
  return result;
}
