How to remove continued repeated digits in a given number with TypeScript

Answer 1

function removeRepeatedDigits(n: number) {
    let previous_digit: number = n % 10;
    let tens_hundreds_thousands_and_more: number = 10;
    let result: number = previous_digit;
    
    while (n != 0) {
        let current_digit = n % 10;
        if (current_digit != previous_digit) {
            result += current_digit * tens_hundreds_thousands_and_more;
            previous_digit = current_digit;
            tens_hundreds_thousands_and_more *= 10;
        }
        n = Math.floor(n / 10);
    }
    return result;
}
        
let n: number = 951112722221333;
n = removeRepeatedDigits(n);
console.log(n);
