Odd Integers In Range Program in Python

Print all odd integers between two given integers, excluding the boundaries.

Understand the Problem

Problem Statement

Write a program that accepts two integers X and Y, then prints all odd integers between them (excluding X and Y themselves).

Constraints

-999999 <= X <= 9999999
X < Y <= 9999999
Output must contain only odd integers
Output must be space-separated

Examples

Example 1

Input

1
11

Output

3 5 7 9

Explanation

Between 1 and 11, the integers are 2,3,4,5,6,7,8,9,10. Among these, the odd integers are 3,5,7,9.

Example 2

Input

24
30

Output

25 27 29

Explanation

Between 24 and 30, the integers are 25,26,27,28,29. Among these, the odd integers are 25,27,29.

Solution

#include <stdio.h>

int main() {
    int x, y;
    scanf("%d", &x);
    scanf("%d", &y);
    
    int first = 1;
    for (int i = x + 1; i < y; i++) {
        if (i % 2 != 0) {
            if (!first) {
                printf(" ");
            }
            printf("%d", i);
            first = 0;
        }
    }
    printf("\n");
    return 0;
}

Time:O(Y-X)

Space:O(1)

Approach:

C Implementation:
1. Read integers X and Y using scanf()
2. Use a loop from (X+1) to (Y-1) to iterate through the range
3. Check if each number is odd using (i % 2 != 0)
4. Print the number if odd, with proper spacing using a 'first' flag to avoid trailing spaces
5. Print newline at the end
