<prompt> Array: 3, 4, 7, 5, 1Kujenga algorithm ufanisi kuhesabu idadi ya vipengele katika safu  <response>: One of the simplest and most efficient ways to count the number of elements in an array is to use the length property of the array. This property returns the number of elements in the array and has a time complexity of O1 since it directly accesses the property without needing to loop over the elements. Heres an example using the input array:pythondef count_elementsarr: count lenarr return count Test the function with the input arrayarr 3, 4, 7, 5, 1result count_elementsarrprintresult 5This function takes the input array, arr, and uses the len function to obtain the number of elements in the array. The result is then returned and can be printed to check the output.
