Hi...is it possible to solve this problem using sliding window method?? If we take by taking 3 elements at a time and defining arr[-1] as the last element and arr[n] as the first element ( 0 based indexing )..Is it possible to solve using this method??

Sir this is my code. I am getting the verdict TLE. Please help me.

#include<iostream>using namespace std;long int arr[200000],res = 0;long int process(int x);int main(){long int n,res,i;cin>>n;for(i=0;i<n;i++){cin>>arr[i];}res = process(n-1);cout<<res;return 0;}long int process(int i){if(i < 2){return 0;}res = min(arr[i] + process(i-1),min(arr[i-1] + process(i-2),arr[i-2] + process(i-3)));return res;

Dear Sir,

I have used the following logic -

At any point (x,y) , f(x,y) = (x,y) + max(f(x-1,y),f(x,y-1)); /// from the top

at this position i have recreated the best paths "from bottom" to the positions..(x,y) (x+2,y) and (x,y+2)..I have then taken out the max of all the three later calculated weightages...and then stored the → f(x) + max value to temp_max variable..and then put it into recursion.so that the new max value is updated at each call...Am i right in my approach??

Hope to get your reply soon.

Thank You
