 5) A left rotation operation on an array shifts each of the array's elements  unit to the left. For example, 
-if 2 left rotations are performed on array [1, 2, 3, 4, 5], then the array would become [3, 4, 5, 1, 2].
+if  left rotations are performed on array [1, 2, 3, 4, 5], then the array would become [3, 4, 5, 1, 2].
 
 Solution: 
+function Shi(arr, n){
+    for(let j = 0; j<n; j++){
+        let a = arr[0];
+        for(let i = 1; i <arr.length; i++){
+            let b = arr[i-1];
+            arr[i-1] = arr[i];
+            arr[i]=arr[i-1];
+        }
+        arr[arr.length-1] = a;
+    }
+    return arr;

 5) A left rotation operation on an array shifts each of the array's elements  unit to the left. For example, 
 if  left rotations are performed on array [1, 2, 3, 4, 5], then the array would become [3, 4, 5, 1, 2].
 
 Solution: 
-function Shi(arr, n){
-    for(let j = 0; j<n; j++){
-        let a = arr[0];
-        for(let i = 1; i <arr.length; i++){
-            let b = arr[i-1];
-            arr[i-1] = arr[i];
-            arr[i]=arr[i-1];
-        }
-        arr[arr.length-1] = a;
-    }
-    return arr;
+function totheLeft(arr, n){
+    var a= arr.splice(0,n);
+    return arr.concat(a);
 }
