TheindexOf()method returns the first index at which a given element can be found in the array, or -1 if it is not present. Thefilter()method creates a shallow copy of a portion of a given array, filtered down to just the elements from the given array that pass the test implemented ...
Given a sorted array, remove the duplicates in place such that each element appear only once and return the new length. Do not allocate extra space for another array, you must do this in place with constant memory. For example, Given input array A = [1,1,2], Your function should retur...
System.out.print("Remove duplicate result: "); // // Create an array to convert the Set back to array. // The Set.toArray() method copy the value in the set to the // defined array. // String[] result =newString[set.size()]; set.toArray(result); for(String s : result) {...
