Squaring something in c++
Web6 Jan 2015 · It can be done in O (n) time. Split your array into two logical parts. Positive and negative. Then apply square to each element in both arrays. Then merge the arrays ( merging can be done in O (n) ), but merge the array with previously negative integers in reverse order, since its values will be reversed. Share Improve this answer WebMethod 1: The idea is based on the fact that the square root of any number n can be calculated by adding odd numbers exactly n times. The relation can be expressed as: 1 2 = 1 2 2 = (1 + 3) = 4 3 2 = (1 + 3 + 5 = 9) 4 2 = (1 + 3 + 5 + 7) = 16 The implementation can be seen below in C++, Java, and Python: C++ Java Python Download Run Code Output:
