JavaScript Solution

/*
 * Complete the 'repeatedString' function below.
 *
 * The function is expected to return a LONG_INTEGER.
 * The function accepts following parameters:
 *  1. STRING s
 *  2. LONG_INTEGER n
 */

function repeatedString(s, n) {
    let countInOriginal = 0; 
    
    for(let c of s) {
        countInOriginal += c === 'a' ? 1 : 0;
    } 
    
    
    let fullRepeats = Math.floor(n / s.length); 
    let count = fullRepeats * countInOriginal; 
    
    let remaining = n % s.length; 
    
    for(let i = 0; i < remaining; i++) {
        count += s[i] === 'a' ? 1 : 0; 
    } 
    
    return count; 
}

Here is my c++ solution, you can watch the explanation here : https://youtu.be/Vh5davsSkfA

long ccount(string s) {
    return count(s.begin(), s.end(), 'a');
}

long repeatedString(string s, long n) {
    return (n / s.size()) * ccount(s) + ccount(s.substr(0, n % s.size()));
}

JavaScript Solution

let length =s.length,count=1,repeactChar='a'; let repetWord = Math.floor(n/length); let remainderChar = n%length;; for(let i = 0; i < length; i++){ if(repeactChar == s[i]) count++; } count = count * repeatWord; for(let j = 0; j < remainderChar; j++){ if(repeactChar ==s[j]) count++; } return count

I have submitted my code in Python 3. But i am seeing runtime error for few of the testcases. Please suggest what need to change.

!/bin/python3

import math import os import random import re import sys

def repeatedString(s, n): # Write your code here if s == 'a': return n elif (1 <= len(s) <= 100) and (1 <= n <=1000000000000): i = int(n / len(s)) st = s * i i = int(n % len(s)) st = st + s[0:i] return (st.count('a')) else: return 0 if name == 'main': fptr = open(os.environ['OUTPUT_PATH'], 'w') s = input() n = int(input().strip()) result = repeatedString(s, n) fptr.write(str(result) + '\n') fptr.close()

Repeated String is such an interesting concept! It reminds me of how important sound quality is in our everyday lives. Speaking of which, have you ever tried using sound deadening composites? They really make a difference in reducing noise levels and creating a more peaceful environment. It's amazing how a little change can enhance our experience!
