Given a square matrix, the task is to find the element of the matrix where the right and the left diagonal of this square matrix converge.
Input: n = 5, matrix = [ 1 2 3 4 5 5 6 7 8 6 9 5 6 8 7 2 3 5 6 8 1 2 3 4 5 ] Output: 6 Input: n = 4, matrix = [ 1 2 3 4 5 6 7 8 9 0 1 2 4 5 6 1 ] Output: NULL Here there no converging element at all. Hence the answer is null.
- If the number of rows and column of the matrix are even, then we just print NULL because there would be no converging element in the case of even number of rows and column.
- If the number of rows and column of the matrix are odd, find the mid-value of n as
mid = n/2
- The arr[mid][mid] itself is the converging diagonal element.
Below is the implementation of the above approach:
- Find smallest and largest element from square matrix diagonals
- Sum of both diagonals of a spiral odd-order square matrix
- Row-wise common elements in two diagonals of a square matrix
- Swap major and minor diagonals of a square matrix
- Center element of matrix equals sums of half diagonals
