Problem: Checking If Two Arrays Can Be Made Equal by Sorting

This README provides a step-by-step explanation of the solution for determining if two arrays can be made equal by sorting them. The problem is solved in multiple programming languages: C++, Java, JavaScript, Python, and Go.

C++ Code Explanation

  1. Include Necessary Headers

    • #include <vector>
    • #include <algorithm>

  2. Define the Solution Class

  3. Define the Method canBeEqual

    • Step 1: Sort the target array.
    • Step 2: Sort the arr array.
    • Step 3: Compare the sorted arrays and return the result of the comparison.

Java Code Explanation

  1. Import Necessary Packages

    • import java.util.Arrays;

  2. Define the Solution Class

  3. Define the Method canBeEqual

    • Step 1: Sort the target array using Arrays.sort.
    • Step 2: Sort the arr array using Arrays.sort.
    • Step 3: Use Arrays.equals to compare the sorted arrays and return the result.

JavaScript Code Explanation

  1. Define the Function canBeEqual

  2. Define the Parameters

    • target: The target array to compare against.
    • arr: The array that needs to be checked for equality.

  3. Function Steps

    • Step 1: Sort the target array in ascending order using Array.prototype.sort.
    • Step 2: Sort the arr array in ascending order using Array.prototype.sort.
    • Step 3: Convert both sorted arrays to strings and compare them. Return true if they are equal, otherwise false.

Python Code Explanation

  1. Import Necessary Modules

    • from typing import List

  2. Define the Solution Class

  3. Define the Method canBeEqual

    • Step 1: Sort the target array using list.sort.
    • Step 2: Sort the arr array using list.sort.
    • Step 3: Compare the sorted arrays and return the result.

Go Code Explanation

  1. Import Necessary Packages

    • import "sort"

  2. Define the Function canBeEqual

  3. Define the Parameters

    • target []int: The target array.
    • arr []int: The array to compare against the target.

  4. Function Steps

    • Step 1: Sort the target array in ascending order using sort.Ints.
    • Step 2: Sort the arr array in ascending order using sort.Ints.
    • Step 3: Iterate over the elements of the sorted arrays.
    • Step 4: Compare each corresponding element. If any pair of elements does not match, return false.
    • Step 5: If all elements match, return true.
