Shuffle String
Difficulty:Easy
How to shuffel the string ?
Problem
Given a string s and an integer array indices of the same length.
The string s will be shuffled such that the character at the ith position moves to indices[i] in the shuffled string.
Return the shuffled string.
Example 1:
Input: s = "codeleet", indices = [4,5,6,7,0,2,1,3]
Output: "leetcode"
Explanation: As shown, "codeleet" becomes "leetcode" after shuffling.
Example 2:
Input: s = "abc", indices = [0,1,2]
Output: "abc"
Explanation: After shuffling, each character remains in its position.
Example 3:
Input: s = "aiohn", indices = [3,1,4,2,0]
Output: "nihao"
Example 4:
Input: s = "aaiougrt", indices = [4,0,2,6,7,3,1,5]
Output: "arigatou"
Example 5:
Input: s = "art", indices = [1,0,2]
Output: "rat"
Constraints:
s.length == indices.length == n
1 <= n <= 100
s contains only lower-case English letters.
0 <= indices[i] < n
All values of indices are unique (i.e. indices is a permutation of the integers from 0 to n - 1).
Recommended: Please try your approach on your integrated development environment (IDE) first, before moving on to the solution.
Few words from CodingHumans : Don't Just copy paste the solution, try to analyze the problem and solve it without looking by taking the the solution as a hint or a reference . Your understanding of the solution matters.
HAPPY CODING 😁
Solution:
( Java )
class Solution {
public String restoreString(String s, int[] indices) {
char[] t = new char[s.length()];
for(int i = 0;i < s.length();i++){
t[indices[i]] = s.charAt(i);
}
return new String(t);
}
}
Solution:
( Python )
class Solution(object):
def restoreString(self, s, indices):
N = len(s)
A = [0] * N
for ix, c in zip(indices, s):
A[ix] = c
return "".join(A)
