Left Rotation in an Array using Java There are two methods implemented by me here :- 1) Using extra Array Get new position of a current element using formula. Add the element in the new position in a new array. 2) Using same Array:- This is little bit complex hold variable at index i. find new index for variable. hold variable present at new index. place variable at index i to this new index. assign i to new index variable. repeat steps until count is not equal to lenght of an array which simply means all variable got covered. package Arrays ; /* * 12345 to 34512 */ /* * sample input * 5 4(d=4 that is 4 rotations) 1 2 3 4 5 sample output 51234 */ public class LeftRotation { public static void printArray ( int [] arr ) { for ( int i =0; i < arr . length ; i ++) { System . out . print ( " " + arr [ i ]); } System . out . println ( " " ); } //method which returns
