Javascript Program to Find maximum element of each row in a matrix Last Updated : 12 Sep, 2024 Summarize Comments Improve Suggest changes Share Like Article Like Report Given a matrix, the task is to find the maximum element of each row.Examples: Input : [1, 2, 3] [1, 4, 9] [76, 34, 21]Output :3976Input : [1, 2, 3, 21] [12, 1, 65, 9] [1, 56, 34, 2]Output :216556Approach : Approach is very simple. The idea is to run the loop for no_of_rows. Check each element inside the row and find for the maximum element. Finally, print the element. Below is the implementation : JavaScript // javascript program to find maximum // element of each row in a matrix // Function to get max element function maxelement(no_of_rows, arr) { let i = 0; // Initialize max to 0 at beginning // of finding max element of each row let max = 0; let result = Array.from({ length: no_of_rows }, (_, i) => 0); while (i < no_of_rows) { for (let j = 0; j < arr[i].length; j++) { if (arr[i][j] > max) { max = arr[i][j]; } } result[i] = max; max = 0; i++; } printArray(result); } // Print array element function printArray(result) { for (let i = 0; i < result.length; i++) { console.log(result[i]); } } // Driver code let arr = [[3, 4, 1, 8], [1, 4, 9, 11], [76, 34, 21, 1], [2, 1, 4, 5]]; // Calling the function maxelement(4, arr); // This code is contributed by 29AjayKumar Output8 11 76 5 Complexity Analysis:Time Complexity: O(N*M), where N is the number of rows and M is the number of columns in the given matrix.Space Complexity: O(N), where N is the number of rows in the given matrix.Please refer complete article on Find maximum element of each row in a matrix for more details!
