//* Programming Challenge: Mobile Number Validation
//*-
//? Write a function that takes a string as input and returns true if the string repres a valid Indian mobile number, and false otherwise.
//* Validation Requirements:
//? Length: An Indian mobile number should have exactly 10 digits.
//? Starting Digit: The number must start with 6, 7, 8, or 9, which are valid starting digits for Indian mobile numbers.
// Test Cases

function validateIndianMobileNumber(number) {
    // Regular expression to match Indian mobile numbers
    var regex = /^[6-9]\d{9}$/;
    
    // Test the input number against the regex
    return regex.test(number);
}

// Test Cases
console.log(validateIndianMobileNumber("9876543210")); // Expected output: true
console.log(validateIndianMobileNumber("0123456789")); // Expected output: false
console.log(validateIndianMobileNumber("897654321"));  // Expected output: false
console.log(validateIndianMobileNumber("78965432107")); // Expected output: false


console.log(validateIndianMobileNumber("9876543210")); // Expected output: true console.log(validateIndianMobileNumber("0123456789)); // Expected output: false console.log(validateIndianMobileNumber("897654321" )); // Expected output: false console.log(validateIndianMobileNumber("78965432107"));
