Serialize

Problem Description

You are given an array A of strings and we have to serialize it and return the serialized string.

Serialization: Scan each element in a string, calculate its length and append it with a string and a element separator or deliminator (the deliminator is ~). We append the length of the string so that we know the length of each element.

For example, for a string 'interviewbit', its serialized version would be 'interviewbit12~'.

Problem Constraints

1 <= |A| <= 1000
1 <= |A_i| <= 1000
A_i only contains lowercase english alphabets.

Input Format

The first argument A is the string array A.

Output Format

Return a single integer denoting the serialized string.

Example Input

Input 1:

A = ['scaler', 'academy']

Input 2:

A = ['interviewbit']

Example Output

Output 1:

scaler6~academy7~

Output 2:

interviewbit12~

Example Explanation

Explanation 1:

Length of 'scaler' is 6 and academy is 7. So, the resulting string is scaler6~academy7~.

Explanation 2:

Explained in the description above.

NOTE: You only need to implement the given function. Do not read input, instead use the arguments to the function. Do not print the output, instead return values as specified. Still have a question? Checkout Sample Codes for more details.
