/* Write a C function that calculates the required heater activation time
according to the input temperature of water.
- if input temperature is from 0 to 30, 
then required heating time = 7
mins.
- if input temperature is from 30 to 60, then 
required heating time = 5
mins.
- if input temperature is from 60 to 90, 
then required heating time = 3
mins.
- if input temperature is more than 90, then 
required heating time = 1
mins.
- if temperature is invalid (more than 100), return 0
Example:
Input = 10 → output = 7
Input = 35 → output = 5 */
