One more thing to add, don’t directly look for the solutions, first try to solve the problems of Hackerrank by yourself. If you find any difficulty after trying several times, then you can look for solutions.

Polar Coordinates in Python HackerRank Solution

Polar coordinates are an alternative way of representing Cartesian coordinates or Complex Numbers.
A complex number z
is completely determined by its real part x and imaginary part y.
Here, j is the imaginary unit.

A polar coordinate (r, q)is completely determined by modulus r and phase angle q.
if we convert complex number z to its polar coordinate, we find:r : Distance from z to origin, i.e., √(x^2+y^2)
q : Counter clockwise angle measured from the positive x-axis to the line segment that joins z to the origin.

Python’s cmath module provides access to the mathematical functions for complex numbers.
cmath.phaseThis tool returns the phase of complex number z(also known as the argument of z).

>>> phase(complex(-1.0, 0.0))
3.1415926535897931

absThis tool returns the modulus (absolute value) of complex number z.

>>> abs(complex(-1.0, 0.0))
1.0

Task :

You are given a complex z. Your task is to convert it to polar coordinates.

Input Format :

A single line containing the complex number z. Note: complex() function can be used in python to convert the input as a complex number.

Constraints :

Given number is a valid complex number

Output Format :

Output two lines:
The first line should contain the value of r.
The second line should contain the value of q.

Sample Input :

 1+2j

Sample Output :

 2.23606797749979
 1.1071487177940904
