How to use bitwise operations In Javascript
In this approach, we first count the number of wildcard characters (‘X’) in the pattern. Then, we iterate from 0 to 2^wildcardCount – 1, generating all possible binary numbers within that range. For each binary number, we replace the wildcard characters in the pattern with the corresponding binary digits and print the resulting binary string.
Example:
function generateBinaryStrings(str) {
// Convert the input pattern into an array for easier manipulation
let pattern = str.split('');
// Find the total number of wildcard characters ('X') in the pattern
let wildcardCount = pattern.reduce((count, char) => char === 'X'
? count + 1 : count, 0);
// Generate all possible binary numbers from 0 to 2^wildcardCount - 1
for (let i = 0; i < Math.pow(2, wildcardCount); i++) {
// Convert the number to binary representation
let binary = i.toString(2).padStart(wildcardCount, '0');
// Replace wildcard characters ('X') with binary digits
let result = pattern.map(char => char === 'X'
? binary.charAt(0) : char).join('');
// Print the generated binary string
console.log(result);
}
}
const pattern = 'X1X';
generateBinaryStrings(pattern);
Output
010 010 111 111
JavaScript Program to Generate all Binary Strings From Given Pattern
In this article, we are going to learn about Generating all binary strings from a given pattern in JavaScript. Generating all binary strings from a given pattern involves creating a set of binary sequences that follow the pattern’s structure, where specific positions in the sequences can be filled with ‘0’ or ‘1’ based on the pattern’s placeholders or rules.
