LeetCode 566. Reshape the Matrix Solution Explained - Java

[@alibaba888]

Going through the columns first made a lot of sense, thanks!

[@rupaldesai7098]

Congratulations on your new job!

[@NickWhite]

Thank you so much!

[@satyamgupta6030]

thanks nick ur videos are helping me alot these day.

[@akshatkumar7526]

much more easier than the solutions on the discussion forum 👍

[@f3-faithfitnessfinance]

Yeah dude. .. don't stop doing these videos
And congrats on your new job👍

[@NickWhite]

thank you dude I appreciate it

[@franksu4459]

I forgot the column_num = 0 when column_num = c. Good stuff

[@sarvarkhalimov111]

How do you come up with such idea like the 1st if statement check? what would you advise to do?

[@MrSaurus]

The program says that the new array needs to hold the exact same number of data as the original array, so that is where he came up with using that first if statement

[@ieltsbaba8400]

I feel that instead of "columns_num==c" this should be "column_num %c ==0". Do you also think the same?

class Solution {
public int[][] matrixReshape(int[][] mat, int r, int c) {

if(r*c != mat.length*mat[0].length) return mat;
int[][] new_mat = new int[r][c];

int row = 0;
int col = 0;

for(int i=0;i

[@Flyingpandit]

class Solution:
def matrixReshape(self, mat, r: int, c: int):
rows=len(mat)
columns=len(mat[0])
if (rows*columns)!=(r*c):
return mat
empty_list=[]
row_no=0
column_no=0
output = np.array([[0]*c]*r)
for i in range(rows):
for j in range(columns):
output[row_no][column_no]=mat[i][j]
column_no+=1
if (column_no==c):
column_no=0
row_no+=1
return output.tolist()

[@sourin.majumdar]

Would the space complexity be O(r*c) ?

[@shubhamtiwari6660]

All the best dude.

[@JavaAidTutorials]

Nice one bro..

[@NickWhite]

what's with the dot dot bro..

[@NickWhite]

i'm getting mixed signals here

[@NickWhite]

i hate you i love you i hate that i love you

@@NickWhite I did not get this 🤔

[@firecracker-i2h]

as programming channel you wont get much views but you will get more subscriber if u are a good programmer

[@praveen3123]

Bro. Can you please solve some graphs problems??

[@f3-faithfitnessfinance]

Leetcode Problem 873 please!!

[@NickWhite]

I’ll check it out!

[@BishalECE-uy5rn]

What about the time complexity

[@valkon_]

Probably O(rows * columns)

[@chodingninjas7415]

do more problems please

[@nadaemam5943]

lol why the f couldnt i solve this i am tired
