2796. Repeat String

Easy

Problem Explanation

Explanation:

To repeat a given string s multiple times, we can simply concatenate the string with itself n times. We will provide solutions in Java, C++, and Python to demonstrate how to implement this algorithm.

  • Algorithm:

    1. Initialize an empty string result.
    2. Iterate n times and concatenate the given string s to the result string in each iteration.
    3. Return the final result string.

  • Time Complexity: O(n * |s|), where n is the number of times to repeat the string and |s| is the length of the input string.

  • Space Complexity: O(n * |s|), the space used to store the repeated string.

Solution Code

class Solution {
    public String repeatString(String s, int n) {
        StringBuilder result = new StringBuilder();
        for (int i = 0; i < n; i++) {
            result.append(s);
        }
        return result.toString();
    }
}
