/*
Problem statement
Data type refers to the type of value a variable has and the way the computer interprets it.
Each data type has a different size. You’ve studied 5 different data types and the sizes of the data types:
Integer: 4 bytes
Long: 8 bytes
Float: 4 bytes
Double: 8 bytes
Character: 1 byte
You’re given a data type. Print its size in bytes.
Example :
Input: Long
Output: 8
Explanation: The size of a Long variable is given as 8 bytes.
Detailed explanation ( Input/output format, Notes, Images )
Sample Input 1:
Long
Sample Output 1:
8
Explanation of sample input 1 :
The size of a Long variable is given as 8 bytes.
Sample Input 2:
Float
Sample Output 2:
4
Explanation of sample input 2 :
The size of a Float variable is given as 4 bytes.
Expected time complexity :
The expected time complexity is O(1).
Constraints :
‘type’ is one of the data types given above.
Time limit: 1 second
