In the previous article, we have discussed Python Program to Check if Two Numbers are Equal Without using Arithmetic and Comparison Operators<\/a><\/p>\n

The bitwise operator can be used to multiply a value by seven. Subtract the original number from the shifted number and return the difference (8n \u2013 n) by left shifting the number by 3 bits (you’ll receive 8n).<\/p>\n

Give a number the task is to get the multiplication of the given number by 7 in an efficient way.<\/p>\n

Examples:<\/strong><\/p>\n

Example1:<\/strong><\/p>\n

Input:<\/strong><\/p>\n

Given Number = 5<\/pre>\n

Output:<\/strong><\/p>\n

After multiplying the given number{ 5 } by 7 =  35<\/pre>\n

Example2:<\/strong><\/p>\n

Input:<\/strong><\/p>\n

Given Number = 3<\/pre>\n

Output:<\/strong><\/p>\n

After multiplying the given number{ 3 } by 7 =  21<\/pre>\n

Program for Efficient Way to Multiply With 7 in Python<\/h2>\n

Below are the ways to get the multiplication of the given number by 7 in an efficient way in Python:<\/p>\n
