PROBLEM:

Chef bought items worth X rupees, and receives some flat discount on them depending on the value of X. What is the final amount paid by Chef?

EXPLANATION:

This is a standard application of the if-else condition found in most languages. There are 4 conditions and exactly one of them is true, so check all 4, subtract the available discount, and print the answer.

  • If X \leq 100, there is no discount so print X
  • Else, if 100 \lt X \leq 1000, print X - 25
  • Else, if 1000 \lt X \leq 5000, print X - 100
  • Else, print X - 500

TIME COMPLEXITY:

\mathcal{O}(1) per test case.

CODE:

Editorialist's Code (Python) 
for _ in range(int(input())):
    x = int(input())
    if x > 5000:
        x -= 500
    elif x > 1000:
        x -= 100
    elif x > 100:
        x -= 25
    print(x)
