Coding problem2
There were 2 coding questions and 10 MCQ questions
1. Binary Numbers

0/40
Asked in companies
Given a number ‘N’, you are supposed to calculate the number of 1s in the binary representation of the given number.
For example:
Given ‘N’ = 4,
Its binary representation is 0..0100, therefore there is only 1 set bit, hence the answer will be 1.
Problem approach
Step 1: Check if the number is greater than 0
Step 2: if the number is >0 then find mod by 2 of that number and store in the string
Step 3: now divide that number by /2
Step 4: Repeat this process until number >0
Step 5: Now print the string in reverse order.
2. Circle Intersection

Asked in companies
You have been given the coordinates of the center of two circle by (‘X1’,’Y1’) and (‘X2’,’Y2’) respectively with radius ‘R1’ and ‘R2’ you have to find if they intersect each other or not. If they are touching each other that is also called an intersection here.
Example:
Input: X1 = 0, Y1 = 0, X2 = 2, Y2 = 0, R1 = 1, R2 = 1
Output: YES
Circles intersect with each other at (1,0) with each other. Refer to the image given below:
Problem approach
Step 1 : calculate the distance between two centers of circle using the formula
C1C2 = sqrt((x1 – x2)2 + (y1 – y2)2).
Step 2 : There are 3 cases :
case 1:C1C2 == R1 + R2: Circle A and B are touch to each other.
case 2:C1C2 > R1 + R2: Circle A and B are not touch to each other
case 3:C1C2 < R1 + R2: Circle intersects each other.
Step 3 : using above mentioned cases we can find the answer.
