[@reddygopichand2002]

Understood thanks 👍🙏

[@lucario404]

edge cases are mat[m][1] and mat[1][n], because of which 2 checks are needed

[@akashverma5756]

Simulation approach is more intuitive and clean if you uderstand direction co-ordinate. Direction co-ordinate help you solve many other matrix problems easily.

[@navkaransingh3948]

Bro, wdym by simulation approach?

[@harshilpatel3205]

Understood 🙏🏻

[@neoh1471]

your solution is good, but i have another idea, i'm using javascript shift(), pop() and reverse() to get the array element into my answer array, then every time i process a row, i'll transpose the matrix and i will reverse() it if needed, then repeat untill the matrix become empty, and print the answer array. All code is written in a while loop with lambda functions. let ans = [] while(matrix.length != 0){ matrix.shift().forEach(x => ans.push(x)); if(matrix.length == 0) break; matrix = matrix[0].map((_,colIndex) => matrix.map(row => row[colIndex])); matrix.pop().forEach(x => ans.push(x)); if(matrix.length == 0) break; matrix = matrix[0].map((_,colIndex) => matrix.map(row => row[colIndex])); matrix.pop().reverse().forEach(x => ans.push(x)); if(matrix.length == 0) break; matrix = matrix[0].map((_,colIndex) => matrix.map(row => row[colIndex])); matrix.shift().reverse().forEach(x => ans.push(x)); if(matrix.length == 0) break; matrix = matrix[0].map((_,colIndex) => matrix.map(row => row[colIndex])); } // print ans here
