Hey @raghav007
When u traverse a grid then u use a 2D Array to store/access some value
But u are are traversing only with the help of ur logic not with the help of that array
Its only there to provide u with some info like say u have to calculate cost of each path then u need cost of each tile hence u need that array.

I hope u got my point
