krishnamurthy GET endpoint does not read number from request body

[YuvalG724]

Bug: The /krishnamurthy endpoint is defined as GET but tries to read req.body.number.
GET requests don’t have a body, so the endpoint always fails.

Steps to Reproduce:

1. Run the server: node app.js
2. Send GET request:
   http://localhost:5000/krishnamurthy?number=145
3. Observe that the endpoint does not respond correctly.

Expected Behavior:
The server should respond with:
{
"message": "The Number is a Krishnamurthy Number"
}

Actual Behavior:
The server cannot read the number and returns undefined or an error.
