Objective 

Today we're expanding our knowledge of strings and combining it with what we've already learned about loops.

Task 

Given a string, S, of length N that is indexed from 0 to N - 1, print its even-indexed and odd-indexed as 2 space-separated strings on a single line.

Note: 0 is considered to be an index.

Input Format 

The first line contains an integer, T (the number of test cases).

Each line i of the T subsequent lines contains a String, S.

Constraints 

• 1 ≤ T ≤ 10
• 2 ≤ length of S ≤ 10000

Output Format 

For each String Sj (where 0 ≤ j ≤ T - 1), print Sj's even-indexed characters, followed by a space, followed by Sj's odd-indexed characters.

Sample Input 

2
Hacker 
Rank 

Sample Output 

Hce akr 
Rn ak 

Explanation 

Test Case 0: S = "Hacker"

S[0] = "H"

S[1] = "a" 

S[2] = "c"

S[3] = "k"

S[4] = "e"

S[5] = "r"

The even indices are 0,2 and 4, and the old indices are 1,3 and 5. We then print a single line of 2 space-separated strings; the first string contains the ordered characters from S's even indices (Hce), and the second string contains the ordered characters from S's odd indices (akr).

Test Case 1: S = "Rank"

S[0] = "R" 

S[1] = "a"

S[2] = "n"

S[3] = "k"

The even indices are 0 and 2, and the odd indices are 1 and 3. We then print a single line of 2 space-separated strings; the first string contains the ordered characters from S's even indices (Rn), and the second string contains the ordered characters from S's odd indices (ak).

Solution - Day 6: Let's Review

Python 3 

# Enter your code here. Read input from STDIN. Print output to STDOUT
T = int(input())
for i in range (0 , T):
    S = input()
    print(S[0::2] + " " + S[1::2])
