Given marks of a student, print on the screen:

Grade A if marks >= 90
Grade B if marks >= 70
Grade C if marks >= 50
Grade D if marks >= 35
Fail, otherwise.

For printing use:-

for C++ : cout << variable_name;
for Java : System.out.print();
for Python : print()
for Javascript : console.log()

Please point to new line after you print the output.

Examples:

Input: marks = 95

Output: Grade A

Explanation: marks are greater than or equal to 90.

Input: marks = 14

Output: Fail

Explanation: marks are less than 35.

Input: marks = 70

Constraints

0 <= marks <= 100

Editorial

Approach:

Receive Input: Capture the integer input marks from the user.
Conditional Check:
- If marks are greater than or equal to 90, print "Grade A".
- If marks are greater than or equal to 70 but less than 90, print "Grade B".
- If marks are greater than or equal to 50 but less than 70, print "Grade C".
- If marks are greater than or equal to 35 but less than 50, print "Grade D".
- If marks are less than 35, print "Fail".

    solution.studentGrade(parseInt(marks));
    readline.close();
});

Complexity Analysis:

Time Complexity: O(1), The operations of receiving input and printing output are executed once regardless of the size of the input.
Space Complexity: O(1), Using only a single variable to store marks, and no additional space is used that grows with the input size.
