#Free Education For All.. # Bhishma Pitamah of DSA...You could have earned in lacs by putting it as paid couses on udamey or any other elaerning portals, but you decided to make it free...it requires a greate sacrifice and a feeling of giving back to community, there might be very few peope in world who does this...."विद्या का दान ही सर्वोत्तम दान होता है" Hats Off to you man, Salute from 10+ yrs exp guy from BLR, India.....

[@AbhinayKrishna4]

Man you literally are a lifesaver, providing such a one stop destination for all the coding questions required to crack any interview.Thanks, striver for your dedication and hard work towards providing quality content.

[@navkaransingh3948]

Hi striver, i think you already know but these series will be legacy for future coding students So, i hope you don't rush this series I'm saying this because i am seeing a lot of comments saying to complete it very fast.

[@takeUforward]

Yes I will be going at my pace, don't want to compromise on quality.

[@juliechoudhary9582]

This course is really worth more than any course but still it is free.Thank you so much.

[@habeeblaimusa4466]

@takeUforward The solution can be simplified by removing the if conditions on internal for loops and writing the exit condition of the while loop as while(ans.length < m * n) This way the loop will never run if all the cells have been visited

this was good, thank you bhrata :)

[@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

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

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

If there is already a while loop that says top

[@Om_parekh001]

agar 1 hi row ka matrix he to according to while loop condition wo andar jayega ek row print hogi .... abhi jo right to left ka loop he use nahi pata ki 1 hi row he and wo cross ho chuki he so...usko rukane ke lie
