Problem statement

You are given an integer ‘N’. You have to print integers from 1 to N.

For Example:

Input: 'N' = 6

Output: 1 2 3 4 5 6

If 'N' = 6, The numbers from 1 to 6 are 1, 2, 3, 4, 5, 6.
Hence, the output will be 1 2 3 4 5 6.

Detailed explanation ( Input/output format, Notes, Images )

Input Format :

The first line of the input contains an integer, 'T’, denoting the number of test cases.

The first and only line of each test case will contain a single integer ‘N’.

Output Format :

For each test case, print the integers from 1 to N separated by spaces.

Print a separate line for each test case.

Note :

You do not need to print anything, it has already been taken care of. Just implement the given function.

Constraints :

1 <= T <= 10
1 <= N <= 10^4

Time limit: 1 sec

Sample Input 1 :

2
6
2

Sample output 1 :

1 2 3 4 5 6
1 2

Explanation For Sample Output 1 :

For the first test case:
N = 6 
The numbers from 1 to 6 are 1, 2, 3, 4, 5, 6.
Hence, the output will be 1 2 3 4 5 6.

For the second test case:
N = 2 
The numbers from 1 to 2 are 1, 2.
Hence, the output will be 1 2.

Sample Input 2 :

2
3
4

Sample output 2 :

1 2 3
1 2 3 4

Hint 1

Hint 2

Run a loop from 1 to N and print each number.

Approaches (2)

Approach 1

Approach 2

Iterative

Run a for loop from 1 to N and print each number.

Here is the algorithm:

Declare a vector ‘ans’ to store numbers.
Iterate over the range from 1 to N (say iterator ‘i’)
- Push ‘i’ into ‘ans’ vector.

Time Complexity

O(N), where ‘N’ is the given integer.

We have traversed each number from 1 to N exactly once.

Hence, the overall time complexity will be O(N).

Space Complexity

O(1)

We are not using any extra space.

Hence the overall space complexity will be O(1).

(100% EXP penalty)
