This is a scratch drill — your code runs, nothing is graded or recorded. No test cases, no expected output, no verdict.

TASK

Complete the check for matrix A. Use the square-dimension guard and one nested row-major traversal, return false at the first mismatch, including A[1][2], and return true only after every position passes. Print the result as false.
