NQueen problem backtracking

#1

there is a use of function nextqueen rakhpaye…
what is the use of return ture in if condtion of if(nextqueenrakhpaye)…
i can’t understand the use of return ture here ans in base conditon also…

#2

in base case we return true to tell that we have placed queen in all rows hence question is solved so we have to return true
if(row>n)return true;

if we can place the queen in that row and also able to solve for other rows
so it will give us true hence we also have to return true to tell that we have placed queen and my work is done
