Number of Palindromic paths in a matrix

Number of Palindromic paths in a matrix is a DSA topic. In plain words you use it for a short Number of Palindromic paths in a matrix example in a short dry-run on paper. Don’t start with a slogan — start with that picture.

Smallest example: the smallest Number of Palindromic paths in a matrix example you can type. Type it, run it, and say what you see. If you can do that from memory, you know Number of Palindromic paths in a matrix.

From the example next to this theory: Number of Palindromic paths in a matrix — arrays give O(1) index access; matrices are arrays of arrays.

Trap: only saying “Number of Palindromic paths in a matrix” with no example. Fix that before you talk about advanced DSA.

Viva: what is Number of Palindromic paths in a matrix? Then show the smallest Number of Palindromic paths in a matrix example you can type. Then name the trap.

Exam tip

What is Number of Palindromic paths in a matrix? Show this: the smallest Number of Palindromic paths in a matrix example you can type. Trap: only saying “Number of Palindromic paths in a matrix” with no example.

Example

arr = [10, 20, 30, 40]
print(arr[2], arr[-1])
matrix = [[1, 2], [3, 4]]
print(matrix[1][0])  # 3

Number of Palindromic paths in a matrix — arrays give O(1) index access; matrices are arrays of arrays.
