Can Buy Item
Programming Basics · Python
TASK
Problem
Given `balance` and `price`, print `YES` if the balance is enough, otherwise `NO`.
EXAMPLE
Example
500 499
YES
LIMITS
Constraints
All integer inputs have absolute value at most 10^9; any additional relationships between them are stated directly in the task.

Theory for this problem
+
`input()` reads data entered by the user. The result of `input()` is initially a string. `split()` separates one input line into individual values using spaces. `map()` applies the specified conversion to each input value. Comparison operators `==`, `!=`, `<`, `>`, `<=`, `>=` compare values and produce `True` or `False`. `if` checks a condition and runs its block when the condition is true. `else` runs when the corresponding `if` condition is false. `print()` displays the program result. Print only what the problem statement requires.
**Connection to this task.** An `if` statement chooses a program branch from a Boolean condition. Comparisons produce `True` or `False`, and `elif` lets you test several mutually exclusive cases in order. The expression `'YES'` shows how this idea is applied to the task data.
For this task, pay special attention to `map(int, input().split())`: it connects the concept above to the concrete computation or program action.
**Focus: “Can Buy Item”.** The same basic mechanism is used in a different context here, so understand the operation itself rather than memorizing a finished line of code.

ANSWER
Solution

balance, price = map(int, input().split())
if balance >= price:
print('YES')
else:
print('NO')
