Whats the error in this?

#1
#2

@Namanjain123
hello Naman,
ur code is running in infinit loop.

for example if u are at (i,j)
a) from -> i,j we can reach (i-1,j) ,(i,j+1),(i+1,j), (i,j-1)

b) now consider (i+1,j) -> (i,j) , (i+2,j),(i+1,j-1) ,(i+1),(j-1)

again from (i,j)-> same story it will give (i+1,j) which will again give (i,j) and this loop will run for infinite time

#3

but when i come from i+1,j to i,j with true value then it will return true to previous call it wont go to the calls beneath it??? i will go below only when we return with false value??

#4

@Namanjain123
but when i+1,j will return false u will again come back to i,j and again same trversal will start

#5

to avoid it just add this extra condition
