JavaScript - Checking for pandigital numbers
A pandigital number is a number that contains all digits (0-9) at least once. We are required to write a JavaScript function that takes in a string representing a number. The function returns true if the number is pandigital, false otherwise.
Example
Following is the code to check for pandigital numbers −
const numStr1 = '47458892414';
const numStr2 = '53657687691428890';
const isPandigital = numStr => {
let legend = ['0', '1', '2', '3', '4', '5', '6', '7', '8', '9'];
for(let i = 0; i < numStr.length; i++){
if(!legend.includes(numStr[i])){
continue;
};
legend.splice(legend.indexOf(numStr[i]), 1);
};
return !legend.length;
};
console.log(isPandigital(numStr1));
console.log(isPandigital(numStr2));Output
Following is the output in the console −
false true
