URI / BEE CROWD 1146 - Growing Sequences - Solution in C,C++,Python,JavaScript:

Your program must read an integer X indefinited times (the program must stop when X is equal to zero). For each X print the sequence from 1 to X, with one space between each one of these numbers.

PS: Be carefull. Don't leave any space after the last number of each line, otherwise you'll get Presentation Error.

Input

The input file contains many integer numbers. The last one is zero.

Output

For each number N of the input file, one output line must be printed, from 1 to N like the following example. Be careful with blank spaces after the last line number.

Input Sample	Output Sample
5 10 3 0	1 2 3 4 5 1 2 3 4 5 6 7 8 9 10 1 2 3

N.B: Don't copy paste the code as same. Just try to understand it and try yourself.

  URI / BEE 1146 Solution in C :   

URI / BEECROWD Online Judge 1146 Solve  in C :

#include <stdio.h>
int main()
{
    int a,b;
    while(1)
    {
        scanf("%d", &a);
        if(a==0) break;
        else
        {
            for(b=1; b<a; b++)
                printf("%d ",b);
        }
        printf("%d\n",a);
    }
    return 0;
}

In this solution, we first read an integer 'a' using the scanf function. Then we use a while loop to continue reading integers until the value of "a" is zero.

Inside the while loop, we use a for loop to print the numbers from 1 to "a", one space apart. We use the printf function to print each number and a space character, and we use the "\n" character to print a newline after the last number in each line.

URI / BEE 1146 Solution in C++ :   

URI / BEECROWD Online Judge 1146 Solve  in C++ :

#include <iostream>

using namespace std;

int main(){
    
    int n;
    
    while(true){
                cin >> n;
                if(n == 0) break;
                for(int i = 1; i <= n; i++){
                        cout << i;
                        cout << ((i == n) ? "\n" : " "); 
                }
    }
    return 0;
}

It's similar to the C program but it uses the cin and cout instead of scanf and printf.

  URI / BEE 1146 Solution in Python :   

URI / BEECROWD Online Judge 1146 Solve  in Python :

while True:
    x = int(input())
    if x == 0:
        break
    else:
        for b in range(1, x):
            print(b, end=' ')
    print(x)

It uses the input() function to read an integer and while loop to continue reading integers until the value of x is zero. 

Inside the while loop, we use a for loop to print the numbers from 1 to x, one space apart. We use the print function to print each number and a space character, and we use the end=' ' in print function to print space after each number.

  URI / BEE 1146 Solution in JavaScript :   

URI / BEECROWD Online Judge 1146 Solve  in JavaScript (Node.Js):

const readline = require('readline');

const rl = readline.createInterface({
    input: process.stdin,
    output: process.stdout
});

rl.on('line', (line) => {
    let a = parseInt(line);
    if (a === 0) {
        rl.close();
    } else {
        for (let b = 1; b < a; b++) {
            process.stdout.write(b + " ");
        }
        console.log(a);
    }
});

In this solution, we use the readline module to read input from the command line. 

The readline.createInterface() function is used to create an interface for reading input and writing output. The on method is used to handle the input event, which is triggered when a new line is entered. 

Inside the event handler, we use a for loop to print the numbers from 1 to a, one space apart. The process.stdout.write() function is used to write output to the command line, similar to console.log() in javascript.
