How to use Queue In Javascript
In this approach,
- We use a queue to iteratively generate binary strings from the ‘X’ pattern.
- Expands the queue by appending ‘0’ and ‘1’ for ‘X’ characters or preserving non-‘X’ characters.
- Prints valid binary strings when they reach the pattern’s length.
Example: In this example, we are using the above-explained approach.
function generateBinaryStrings(str) {
const queue = [''];
for (let i = 0; i < queue.length; i++) {
const current = queue[i];
if (current.length === str.length) {
console.log(current);
} else {
const nextIndex = current.length;
if (str[nextIndex] === 'X') {
queue.push(current + '0');
queue.push(current + '1');
} else {
queue.push(current + str[nextIndex]);
}
}
}
}
const result = 'X1X';
generateBinaryStrings(result);
Output
010 011 110 111
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.
