error

Hey @nmaurya760
Error is on line 30 it should be dp[i][j]=-1
If u still face the issue let me know

#3

Error is coming now also

#4

Ok so
add j>0 here if(obstacleGrid[i][j-1] != 1){
and i>0 here if(obstacleGrid[i-1][j] != 1){

This removes syntatical errors ,now try to debug logically

#5

i am not getting what you are trying to say…

#6

Instead of

if(obstacleGrid[i][j-1] != 1){
if(obstacleGrid[i-1][j] != 1){

use

if(j>0&&obstacleGrid[i][j-1] != 1){
if(i>0&&obstacleGrid[i-1][j] != 1){

#7

I have tried this…still runtime error is coming

Hey @nmaurya760
Yes I know that’s why I said try to debug logically yourself.

And I can see many logical errors so it will be better if u see and understand the solution from here if u can’t debug on ur own :https://leetcode.com/problems/unique-paths-ii/solution/
