Karatsuba Algorithm for fast Multiplication of Large Decimal …

WebAlgorithms/Karatsuba.java. * The Karatsuba algorithm is a multiplication algorithm developed by Anatolii Alexeevitch Karatsuba in 1960. * It operates in O (n^log2 (3)) time (~ O (n^1.585)), with n being the number of digits of the numbers we are multiplying together. * Standard grade-school multiplication operates in O (n^2) time. WebWe are given two decimal numbers with a large number of digits (up to 105) as strings, and we need to write an efficient algorithm to find and print their product. For example, Input 1: a = "1234", b="98765" Output 1: "121876010" Input 2: a = "174592649246", b = "5542636194655762654" Output 2: "967703537031717748762448058884" Approach
