text: if the current combination of j , k , l in the set is equal to S [ i ] return this value as this would be the largest d since we are iterating in descending order
code: if ( $ S [ $ i ] == $ S [ $ j ] + $ S [ $ k ] + $ S [ $ l ] ) { $ found = true ; return $ S [ $ i ] ; } } } } } if ( $ found == false ) return PHP_INT_MIN ; }
