Python Program for Products of ranges in an array

Python Program for Products of ranges in an array

You're given an array of numbers and a list of ranges, and you want to find the product of elements for each given range, then the following Python program can accomplish this:

def product_in_range(arr, l, r): """ Returns the product of elements in arr from index l to r (both inclusive) """ prod = 1 for i in range(l, r+1): prod *= arr[i] return prod def main(): arr = [2, 3, 4, 5] ranges = [(0, 1), (1, 3), (0, 3)] for l, r in ranges: print(f"Product for range ({l}, {r}): {product_in_range(arr, l, r)}") if __name__ == "__main__": main()

In the above example:

  • The product_in_range function calculates the product of elements in the given range.
  • We have an array arr = [2, 3, 4, 5].
  • We have a list of ranges ranges = [(0, 1), (1, 3), (0, 3)].
  • The program calculates and prints the product of elements for each range.

You can modify the arr and ranges values to test with different inputs.
