Divide a number by 3 without using *, /, +, -, % operators


Dividing a Number by 3 without Traditional Operators 🚀
Do you enjoy tackling coding challenges and finding creative solutions? Well, we have an interesting one for you today! 🎉
The task at hand is to divide a number by 3 but without using the traditional arithmetic operators such as *
, /
, +
, -
, or %
. 🤯 Don't worry, it might seem tricky at first, but we'll guide you through a couple of easy solutions. Let's dive in! 💪
The Challenge 🧩
Here's the challenge we're trying to solve together:
How would you divide a number by 3 without using
*
,/
,+
,-
,%
operators?
It's important to note that the number can be signed (positive or negative) or unsigned. 📝
Solution 1: Repeated Subtraction ➖➖➖
One of the simplest ways to divide a number by 3 without using the traditional operators is through repeated subtraction. Here's how it works:
Start with the given number, let's call it
num
.While
num
is greater than or equal to 3, subtract 3 fromnum
and increment a counter variable by 1.Once
num
is less than 3, we've found our quotient.
Let's illustrate this with an example. Consider num = 10
. Here's the step-by-step breakdown:
num = 10
counter = 0
10 >= 3? Yes
Counter = 1
num = 7
7 >= 3? Yes
Counter = 2
num = 4
4 >= 3? Yes
Counter = 3
num = 1
1 >= 3? No
In this example, the quotient of 10 divided by 3 using repeated subtraction is 3. 👍
Solution 2: Bitwise Operations 🖥️
If you're up for a more advanced solution, you can use bitwise operations to divide a number by 3 without traditional operators. Here's how it can be done:
Start with the given number,
num
.Right-shift
num
by 1 bit to divide it by 2.Add the original
num
and the right-shiftednum
together.Right-shift the result from step 3 by 1 bit again.
Repeat steps 3 and 4 until the result is less than 3.
Let's demonstrate this approach with the same example as before: num = 10
.
num = 10
Step 2:
num = num >> 1 = 5
Step 3:
num = num + (num >> 1) = 5 + 2 = 7
Step 4:
num = num >> 1 = 3
Result < 3, Stop.
In this example, the quotient of 10 divided by 3 using bitwise operations is also 3. 👏
