Merge Two Dictionaries

You are given two dictionaries in JSON format. Your task is to merge these two dictionaries into one. The merged dictionary should contain all key-value pairs from both dictionaries. In the event of a key conflict, the value from the second dictionary should overwrite the value from the first dictionary. Note that the merge is not recursive: if the value for a key is itself a dictionary, then the value from the second dictionary will replace the entire dictionary from the first.

Example: merging {"a": 1, "b": 2} with {"b": 3, "c": 4} should yield {"a": 1, "b": 3, "c": 4}.

inputFormat

The input consists of two lines. Each line is a valid JSON object representing a dictionary. The first line corresponds to the first dictionary and the second line corresponds to the second dictionary.

outputFormat

Output a single line containing the merged dictionary in JSON format. The resulting JSON object should have all key-value pairs from both input dictionaries, with values from the second dictionary taking precedence in case of duplicates.

{"a": 1, "b": 2}
{"c": 3, "d": 4}

{"a":1,"b":2,"c":3,"d":4}
