text: Cutting a Rod | DP | A Naive recursive solution for Rod cutting problem ; Returns the best obtainable price for a rod of length n and price [ ] as prices of different pieces ; Recursively cut the rod in different pieces and compare different configurations ; Driver program to test above functions
code: class RodCutting { static int cutRod ( int price [ ] , int n ) { if ( n <= 0 ) return 0 ; int max_val = Integer . MIN_VALUE ; for ( int i = 0 ; i < n ; i ++ ) max_val = Math . max ( max_val , price [ i ] + cutRod ( price , n - i - 1 ) ) ; return max_val ; } public static void main ( String args [ ] ) { int arr [ ] = new int [ ] { 1 , 5 , 8 , 9 , 10 , 17 , 17 , 20 } ; int size = arr . length ; System . out . println ( " Maximum ▁ Obtainable ▁ Value ▁ is ▁ " + cutRod ( arr , size ) ) ; } }
