Function to print the sum of maximum two elements from the array
int maxPairSum ( int arr [ ] , int n ) { int max = 0 ; int secondMax = 0 ; if ( arr [ 0 ] > arr [ 1 ] ) { max = arr [ 0 ] ; secondMax = arr [ 1 ] ; } else { max = arr [ 1 ] ; secondMax = arr [ 0 ] ; } for ( int i = 2 ; i < n ; i ++ ) { if ( arr [ i ] > max ) { secondMax = max ; max = arr [ i ] ; } else if ( arr [ i ] > secondMax ) secondMax = arr [ i ] ; } return ( max + secondMax ) ; }
