Check the score of a given binary string

Article Introduction：A sequence of bytes is called a binary string, which holds a binary value. Binary scores are usually expressed in the range 0 to 1, with 1 reserved for perfect models. In the given binary string, if an element is found to be 1, then it is calculated as a fraction and the count sum is increased. Let us illustrate with an example of a binary fraction - the given binary string is 1011010. In the above image, the number 1 appears at index 0, 2, 3 and 5. Therefore, the total score is 4 because there are 4 indicators with a binary score of 1. The given binary string is 0110001. In the image above, the number 1 appears at index 1, 2 and 6. Therefore, the total score is 3 because there are 3 indexes with a binary score of 1. In this article we will find the given binary word

What is php octal?

Article Introduction：PHP octal refers to a way of representing numerical values using octal notation in the PHP programming language. In computer science, a base system is a way to represent numbers. Common base systems include decimal, binary, octal and hexadecimal. The usage scenario of PHP octal is mainly when it is necessary to represent some specific values, such as file permissions, hardware addresses, etc. In these scenarios, using octal values can be more intuitive and convenient to represent and operate. For PHP developers, it is very important to understand and master the use of PHP octal.

Fibonacci binary numbers (no consecutive ones in binary) - O(1) method

Article Introduction：FibbinaryNumbers are numbers that do not have consecutive 1's in their binary representation. However, they can have consecutive zeros in their binary representation. Binary representation is a representation that displays numbers using base 2, with only two digits 1 and 0. Here we will be given a number and need to determine if the given number is a fibbinary number. Input1:Givennumber:10Output:Yes Explanation - The binary representation of the given number 10 is 1010, which indicates that there are no consecutive 1's in the binary form. Input2:Givennumber:12Output:No Explanation − The binary representation of the given number is 1100, which indicates the binary form
