Two Arrays to a Dictionary in C++

Given a vector of strings names and a vector of integers scores of the same length, pair each name with the score at the same index. Return an unordered_map where names[i] is a key and scores[i] is its value.

The names are all different, while two names can have the same score. If names and scores are empty, return an empty unordered_map. The order of the entries doesn't matter.

Example 1:

Input: names = ["Ana", "Ben", "Cara"], scores = [90, 75, 88]
Output: {"Ana": 90, "Ben": 75, "Cara": 88}
Explanation: "Ana" is at index 0 in names, and the score at index 0 is 90. The same goes for "Ben" with 75 and "Cara" with 88.

Example 2:

Input: names = ["Zoe", "Adam"], scores = [60, 60]
Output: {"Zoe": 60, "Adam": 60}
Explanation: Two names with the same score are two different entries.

Example 3:

Input: names = ["Max"], scores = [100]
Output: {"Max": 100}
Explanation: One name gives a single entry.
