text: Maximum difference between a pair of adjacent elements by excluding every element once | Java implementation of above approach ; Function to calculate maximum difference between adjacent elements excluding every array element once ; Traverse the array ; Stores the maximum diff ; Check for maximum adjacent element ; Exclude current element ; Update maximum difference ; Update previous value ; Append the result into a vector ; Print the result ; Driver code
code: import java . util . * ; class GFG { static void maxAdjacent ( int [ ] arr , int N ) { ArrayList < Integer > res = new ArrayList < Integer > ( ) ; for ( int i = 1 ; i < N - 1 ; i ++ ) { int prev = arr [ 0 ] ; int maxi = Integer . MIN_VALUE ; for ( int j = 1 ; j < N ; j ++ ) { if ( i == j ) continue ; maxi = Math . max ( maxi , Math . abs ( arr [ j ] - prev ) ) ; prev = arr [ j ] ; } res . add ( maxi ) ; } for ( int x : res ) { System . out . print ( x + " ▁ " ) ; } System . out . println ( ) ; } public static void main ( String [ ] args ) { int [ ] arr = { 1 , 3 , 4 , 7 , 8 } ; int N = arr . length ; maxAdjacent ( arr , N ) ; } }
