If the length of the string is > 1, do the following: Split the string into two non-empty substrings at a random index, i.e., if the string is s, divide it to x and y where s = x + y. Randomly decide to swap the two substrings or to keep them in the same order. NOTE : DO NOT USE BIG INTEGER LIBRARIES ( WHICH ARE AVAILABLE IN JAVA / PYTHON ). Write your won atof() that takes a string (which represents an floating point value) as an argument and returns its value as double. 3. given strings "12", "10", your answer should be “120”. After a cut, rod gets divided into two smaller sub-rods. I tried doing it in a brute-force way, but I'm looking for an efficient solution. These numbers generally represent hierarchy from major to minor (a is major and d is minor). And this number is a COLORFUL number since the product … Few things before we begin.
