my method works apparently hackerrank it's not fast enough when dealing big numbers. how optimize it? n array size, k number of times array's elements should rotated left. public static int[] arrayleftrotation(int[] a, int n, int k) { int[] holder = new int[n]; for(int m=0; m<k; m++) { for(int b = 0; b<n; b++) { if(b==0) holder[n-1]=a[b]; else holder[b-1]=a[b]; } = holder; holder = new int[n]; } return a; } you can following public static int[] arrayleftrotation(int[] a, int n, int k) { int[] b = new int[n] for(int = 0; i<n; i++) b[i] = a[(i+k)%n] return b; }
