Matrix Element Cube Sum Problem

For a given M x N sized 2D array 'MATRIX', find and return the value of (i * i + j * j) for elements where the sum of the cubes of its digits equals the element itself. Here, 'i' represents the row number ranging from '0' to 'M-1', and 'j' represents the column number ranging from '0' to 'N-1'.

Example:

Input:

T = 2
M = 3, N = 3
MATRIX = [[153, 99, 1], [0, 28, 999], [370, 441, 370]]
M = 2, N = 2
MATRIX = [[370, 8208], [9474, 1634]]

Output:

4, 12
0, 4

Explanation:

In the first test case, for the element 153, since 1³ + 5³ + 3³ = 153, the output is 0*0 + 0*0 = 0. Similarly, for element 370 in position (2,0), the output is 2*2 + 0*0 = 4.

Constraints:

1

Constraints:

1 <= T <= 10
1 <= M <= 100
1 <= N <= 50
1 <= ELEMENT <= 10^9

Note:

If no element satisfies the condition, return -1.
Implement the function without printing anything; the output handling is already managed.

Accepted Answer

Find and return the value of (i * i + j * j) for elements in a 2D array where the sum of the cubes of its digits equals the element itself.

Iterate through the 2D array and check if the sum of the cubes of digits equals the element itself.
Calculate (i * i + j * j) for elements that satisfy the condition.
Return the calculated values as a new 2D array.
If no element satisfies the condition, return -1.
