Inca knots

Statement

Goal

The input data represents knot-records, strings with knots, used by the Incas to store information.

Each knot-record can be a three digit number.

Each digit is represented by a knot group.

Knot groups consists of a specific length of one character type: &

A & in the left group equals 100.
A & in the middle group equals 10.
A & in the right group equals 1.

The knot groups are separated by hyphens. Two in the ends and three between the knot groups.

Example:  --&---&&---&&&--  = 123

Calculate the sum of all the strings, and make a new string representing the total.

Input

Line 1: An integer n for the number of knot-records.
Next n lines: a string representing a knot-record.

Output

Line 1: A knot-record representing the sum of all the knot-records.

Constraints

1 ≤ n ≤ 100
0 ≤ sum( knot-record ) < 1000

Thanks! :)

I like it, it's a good length for a clash of code. I too tripped a bit on the wording and initially thought I should be looking at groups of 3 chars like &&&, &-&, &--, -&- and so on. The example does make it clear, but it took me a minute. Maybe instead of "positions left, middle and right" you can talk about knot groups (as you do later on).

I have changed the statement a bit. Explaining each element in a logical order. Do you think it is clearer now?

Feels like a great puzzle but it took me a while to understand the example. Somehow, I expected to look for 3-character groups and check where was the knot in that group.

Thanks for feedback! I don't understand why you thought that. Could you please explain how I could write it clearer?

✅ Approved the contribution. Comment: This puzzle is deceivingly difficult but still manageable in under 5 minutes. I think it is fun. And the test cases seem to be a good check for the puzzle passing. Cool
