760. Find Anagram Mappings
Problem Explanation
Explanation:
Given two arrays A and B, we need to find an anagram mapping from A to B, such that for each element a in A, there is exactly one element b in B such that b is an anagram of a.
To solve this problem, we can use a HashMap to store the indexes of elements in array B. We iterate over array A and for each element a, we look up its index in the HashMap and add it to the result array.
:
Solution Code
import java.util.*;
class Solution {
public int[] anagramMappings(int[] A, int[] B) {
Map<Integer, Integer> indexMap = new HashMap<>();
for (int i = 0; i < B.length; i++) {
indexMap.put(B[i], i);
}
int[] result = new int[A.length];
for (int i = 0; i < A.length; i++) {
result[i] = indexMap.get(A[i]);
}
return result;
}
