2117. Abbreviating the Product of a Range

Leetcode Solutions

Using Logarithms and Modulo for Abbreviated Product Calculation

  1. Initialize variables for the product suffix, count of trailing zeros, and the sum of logarithms.
  2. Iterate over the range from left to right, for each number:
    • Add its logarithm to the sum of logarithms.
    • Multiply the suffix by the number, remove trailing zeros, and take modulo 10^14.
  3. After the loop, calculate the number of digits and the first 5 digits using the sum of logarithms.
  4. Construct the result string based on the number of digits and the count of trailing zeros.
