Certificate Awarding based on Score

In this problem, you are given a participant's score, an integer in the range \(0 \leq score \leq 100\). Your task is to determine the type of certificate the participant should receive:

• Gold if \(90 \leq score \leq 100\)
• Silver if \(75 \leq score \leq 89\)
• Bronze if \(50 \leq score \leq 74\)
• No certificate if \(score < 50\)

Your solution should read from standard input and print the corresponding certificate type to standard output.
