text: Function prints Intersection of arr1 [ ] and arr2 [ ] m is the number of elements in arr1 [ ] n is the number of elements in arr2 [ ]
code: void printIntersection ( int arr1 [ ] , int arr2 [ ] , int m , int n ) { int i = 0 , j = 0 ; while ( i < m && j < n ) { if ( arr1 [ i ] < arr2 [ j ] ) i ++ ; else if ( arr2 [ j ] < arr1 [ i ] ) j ++ ; else { printf ( " ▁ % d ▁ " , arr2 [ j ++ ] ) ; i ++ ; } } }
