# Check whether an array can be fit into another array rearranging the elements in the array

• Difficulty Level : Easy
• Last Updated : 13 May, 2021

Given two arrays A and B of same size N. Check whether array A can be fit into array B. An array is said to fit into another array if by arranging the elements of both arrays, there exists a solution such that the ith element of the first array is less than or equal to ith element of the second array.
Examples

```Input : A[] = { 7, 5, 3, 2 }, B[] = { 5, 4, 8, 7 }
Output : YES
Rearrange the first array to {3, 2, 7, 5}
Do not rearrange the second array's element.
After rearranging, all Ai<=Bi.

Input : A[] = { 7, 5, 3, 2, 5, 105, 45, 10 }, B[] = { 2, 4, 0, 5, 6, 9, 75, 84 }
Output : NO```

Approach : Sort both the arrays and check whether Ai is less than or equal to Bi for all 0 ≤ i ≤ N. If at any ith position Ai is greater than Bi return false, otherwise return true.
Below is the implementation of the above approach:

## C++

 `// C++ Program to check whether an array``// can be fit into another array with given``// condition.``#include ``using` `namespace` `std;` `// Returns true if the array A can be fit into``// array B, otherwise false``bool` `checkFittingArrays(``int` `A[], ``int` `B[], ``int` `N)``{``    ``// Sort both the arrays``    ``sort(A, A + N);``    ``sort(B, B + N);` `    ``// Iterate over the loop and check whether every``    ``// array element of A is less than or equal to``    ``// its corresponding array element of B``    ``for` `(``int` `i = 0; i < N; i++)``        ``if` `(A[i] > B[i])``            ``return` `false``;` `    ``return` `true``;``}` `// Driver Code``int` `main()``{``    ``int` `A[] = { 7, 5, 3, 2 };``    ``int` `B[] = { 5, 4, 8, 7 };``    ``int` `N = ``sizeof``(A) / ``sizeof``(A);` `    ``if` `(checkFittingArrays(A, B, N))``        ``cout << ``"YES"``;``    ``else``        ``cout << ``"NO"``;``    ``return` `0;``}`

## Javascript

 ``
Output:
`YES`

Time Complexity : O(N * logN), where N is the size of array.
