Problem :[DESTCELL Problem - CodeChef](https://www.codechef.com/problems/DESTCELL)  
[CodeChef: Practical coding for everyone](https://www.codechef.com/viewsolution/26195612)  
In it for each K Firstly, I saw whether or not it is visited  
Then apply condition for i \<= n && j \<= m  
and change i and j accordingly  
According to me each loop will take O((m\*n)/(k+1))  
Can somebody find the reason for TLE  
Thanks in advance 🙂

Firstly, there is no need for that as at max k = 10^6 which is in range  
Secondly, I tried it 😅

I think its because u are initialising the visited array each time .  
Just initialise it one time and mark it unvisited in the loop after counting.
