Shifting the max . The equal condition happens if we shifted the max to arr [ min_i ] in the previous swap .
if ( arr [ min_i ] == max ) swap ( arr , j , min_i ) ; else swap ( arr , j , max_i ) ; } } static int [ ] swap ( int [ ] arr , int i , int j ) { int temp = arr [ i ] ; arr [ i ] = arr [ j ] ; arr [ j ] = temp ; return arr ; }
