Alternate Print Problem Statement

Given two strings A and B, your task is to print these two strings in an alternating sequence by indices. That is, the first character of 'A', the first character of 'B', followed by the second character of 'A', the second character of 'B', and so on.

Example:

Input:

A = "abc", B = "fdh"

Output:

"afbdch"

Explanation:

The characters are alternated from both strings until all characters are used. If any characters are left in one string, they are appended at the end.

Constraints:

1

Alternate Print Problem Statement

Given two strings A and B, your task is to print these two strings in an alternating sequence by indices. That is, the first character of 'A', the first character of 'B', followed by the second character of 'A', the second character of 'B', and so on.

Example:

Input:

A = "abc", B = "fdh"

Output:

"afbdch"

Explanation:

The characters are alternated from both strings until all characters are used. If any characters are left in one string, they are appended at the end.

Constraints:

1 <= T <= 10
1 <= |A|, |B| <= 10^5
A and B contain only lowercase English letters.

Note:

If one string is exhausted and characters remain in the other, append the remaining characters of the other string to the end. You do not need to print anything; the function implementation will handle output.

Accepted Answer

The task is to print two strings in an alternating sequence by indices.

Iterate through both strings simultaneously and append characters alternately
Handle the case where one string is longer than the other
Use two pointers to keep track of the current index in each string
