2614. Prime In Diagonal

Leetcode Solutions

Brute Force Prime Checking on Diagonals

  1. Initialize a variable max_prime to 0 to keep track of the largest prime number found on the diagonals.
  2. Iterate over each index i from 0 to the length of nums minus 1.
    • For each i, check if nums[i][i] (main diagonal) is a prime number. If it is, update max_prime if it's larger than the current max_prime.
    • Check if nums[i][nums.length - i - 1] (secondary diagonal) is a prime number. If it is, update max_prime if it's larger than the current max_prime.
  3. After the loop, return max_prime as the result.
