What is the use of statements after sol[i][j]=0;?

#1

i am bit confused why we did that if statement?

#2

hello @namanmittal0007

when we came to state ( i,j ) then we marked it 1. to indicate that we have come through this way.

but when we r going back to previous state it is our responsibility to mark the state (i,j) as 0 (i,e treat the current state as unexplorered)

#3

no, i was asking about the statement after this statement. i was having doubt with the if(){return true statement } after this

#4

pls paste the code snippet , in which u r having doubt

#5

if( rightsuccess || downsuccess ){
retrun true;
return false;

#6

here we r checking whether we have found any valid path or not.
if we have found any then we are returning true
otherwise we r returning false
