Inside Inclusive Range
Programming Basics · C++
TASK
Problem
Given integers `x`, `l`, and `r` with `l ≤ r`, print `YES` if `l ≤ x ≤ r`; otherwise print `NO`.
EXAMPLE
Example
5 1 10
YES
LIMITS
Constraints
All integer magnitudes are at most 10^9; divisors are non-zero where used.

Theory for this problem
+
`if`, comparison operators, and logical operators let a program choose output according to a condition.
Connection to “Inside Inclusive Range”: here, intermediate values are best kept in named variables so the formula stays readable and data types remain clear.
NEED HELP?
Hints
+
['Write the condition directly and print exactly the required value.', 'After solving “Inside Inclusive Range”, verify the algorithm on your own small example and on an allowed boundary case. Print only the required result with no extra text.']
ANSWER
Solution
+
#include <iostream>
#include <algorithm>
#include <cstdlib>
using namespace std;
int main() {
long long x, l, r;
cin >> x >> l >> r;
cout << (l <= x && x <= r ? "YES" : "NO") << '\n';
return 0;
}
