what is wrong in this code

#2

hey @Tiya, you have skipped backtracking step, interchanged m and n, read matrix at wrong position.
I have made changes to your code, you can check them here https://ide.codingblocks.com/s/131015
But I suggest you to go through the video lecture once to understand the approach.

#3

but in the vdo they had to print all the possible ways so after marking in the 1st time they had to make everything equal to 0 but in this case only one path has to be printed so why would we need to make the 1s 0 again.On encountering a deadend we r returning false so wont that suffice?also does returning false when there is a block ahead also considered as backtracking?

#4

hey @Tiya, I answered your query as per the question where you need to print one path only, For printing all the paths you can refer to video thats also fine.

#5

this getting runtime error

#6

hey @Tiya, share the code which is giving run error and if you are implementing it on some question than please share the question link too.
And please share the code saved in Coding blocks ide as text gets mismatched here.

hey @Tiya, there was small mistake while taking m and n in your code, m is for row and n is for col.
