879119. Multi Printing
Basic
Multi Printing
Summary
The problem is about printing multiple strings in a specific order, given a list of strings and their corresponding print orders. The goal is to find an optimal way to print all the strings according to their original order.
Detailed Explanation
To solve this problem, we can use a simple iterative approach. We iterate over the input list of strings, and for each string, we check its print order. If it's time to print that string (i.e., its turn in the print order), we print it. Otherwise, we skip printing it.
Here's the step-by-step breakdown:
- Initialize an empty list
resultto store the printed strings. - Iterate over the input list of strings.
- For each string:
- Check if it's time to print that string (i.e., its turn in the print order).
- If it is, add it to the
resultlist and increment a counter for the current print order.
- Repeat step 3 until all strings have been processed.
- Return the
resultlist.

Java
import java.util.ArrayList;
import java.util.List;
public List<String> multiPrint(List<String> strings) {
List<String> result = new ArrayList<>();
int currentOrder = 0;
for (String s : strings) {
if (s.startsWith(String.valueOf(currentOrder))) {
result.add(s);
currentOrder++;
}
}
return result;
