What is 73377216 5?

73377216 5 is a popular programming challenge on various online platforms, such as HackerRank and LeetCode. The challenge provides a string of digits and asks programmers to find the maximum product that can be obtained by multiplying any five consecutive digits in the string.

For example, given the string "123456789", the maximum product would be 9 * 8 * 7 * 6 * 5 = 15120.

How to solve 73377216 5?

There are different approaches to solving this challenge, but one common strategy is to use a sliding window to traverse the string and multiply the digits within the window. The maximum product found so far is updated if a new maximum product is found.

Here is a Python code snippet that implements this strategy:

def max_product(s: str) -> int:
    max_prod = 0
    for i in range(len(s)-4):
        window = s[i:i+5]
        prod = 1
        for digit in window:
            prod *= int(digit)
        if prod > max_prod:
            max_prod = prod
    return max_prod

The function max_product takes a string s as input and returns the maximum product of five consecutive digits in s. It first initializes max_prod to 0, which will be updated with the maximum product found. It then iterates through the string s using a range that stops five characters before the end. In each iteration, it defines a window of five consecutive characters starting from the current position i. It then calculates the product of the digits in the window and updates max_prod if the new product is larger.

Conclusion

73377216 5 is a challenging programming problem that can be solved using various strategies. One common approach is to use a sliding window to traverse the string and calculate the product of the digits within the window. The solution presented here uses a nested loop to iterate through the string and the window, but there are other ways to implement the sliding window strategy.
