Program to left rotate the elements of an array

Python

#Initialize array   
arr = [1, 2, 3, 4, 5];   
#n determine the number of times an array should be rotated  
n = 3;  
   
#Displays original array  
print("Original array: ");  
for i in range(0, len(arr)):  
    print(arr[i]),   
   
#Rotate the given array by n times toward left  
for i in range(0, n):  
    #Stores the first element of the array  
    first = arr[0];  
      
    for j in range(0, len(arr)-1):  
        #Shift element of array by one  
        arr[j] = arr[j+1];  
          
    #First element of array will be added to the end  
    arr[len(arr)-1] = first;  
   
print();  
   
#Displays resulting array after rotation  
print("Array after left rotation: ");  
for i in range(0, len(arr)):  
    print(arr[i]),  

Output:

Original array: 
1 2 3 4 5 
Array after left rotation: 
4 5 1 2 3 

C

#include <stdio.h>  
   
int main()

    //Initialize array   
    int arr[] = {1, 2, 3, 4, 5};

    int length = sizeof(arr)/sizeof(arr[0]);  
    //n determine the number of times an array should be rotated  
    int n = 3;  
      
    //Displays original array  
    printf("Original array: \n");  
    for (int i = 0; i < length; i++) {   
        printf("%d ", arr[i]);   
    }    
      
    //Rotate the given array by n times toward left  
    for(int i = 0; i < n; i++){  
        int j, first;  
        //Stores the first element of the array  
        first = arr[0];  
      
        for(j = 0; j < length-1; j++){  
            //Shift element of array by one  
            arr[j] = arr[j+1];  
        }  
        //First element of array will be added to the end  
        arr[j] = first;  
    }  
      
    printf("\n");  
      
    //Displays resulting array after rotation  
    printf("Array after left rotation: \n");  
    for(int i = 0; i < length; i++){  
        printf("%d ", arr[i]);  
    }  
    return 0;  
}  

Output:

Original array: 
1 2 3 4 5 
Array after left rotation: 
4 5 1 2 3
