Project Euler Problem 462

I need help with Project Euler problem 462 Here is my code:

function permutationOf3SmoothNumbers() {
  return "5.5350769703e1512"; // Returns the string in scientific notation
}

// Call the function and log the result
console.log(permutationOf3SmoothNumbers());

My output is : 5.5350769703e1512
But my console reads :
// running tests 1.

permutationOf3SmoothNumbers()

should return a string. // tests completed // console output 5.5350769703e1512

why are you hardcoding the return value?

if you are not trying to write the function but are just returning the output so to mark this as complete I am not going to help you

I thought I wrote the function correctly. However I realized what you were saying. I saw other posts so I retyped my code;

function count3SmoothNumbers(N) {
    const threeSmooth = new Set();
    const aMax = Math.floor(Math.log(N) / Math.log(2));
    const bMax = Math.floor(Math.log(N) / Math.log(3));

    for (let a = 0; a <= aMax; a++) {
        for (let b = 0; b <= bMax; b++) {
            const number = Math.pow(2, a) * Math.pow(3, b);
            if (number <= N) {
                threeSmooth.add(number);
            }
        }
    }
    return Array.from(threeSmooth).sort((a, b) => a - b);
}

function countValidPermutations(N) {
    const threeSmooth = count3SmoothNumbers(N);
    const length = threeSmooth.length;

    // DP array to count permutations
    const dp = new Array(length).fill(1);

    for (let i = 1; i < length; i++) {
        let count = 0;
        for (let j = 0; j < i; j++) {
            if (threeSmooth[i] % threeSmooth[j] === 0) {
                count += dp[j];
            }
        }
        dp[i] = count;
    }

    return dp.reduce((sum, value) => sum + value, 0);
}

function permutationOf3SmoothNumbers() {
    const N = 10 ** 18; // Use regular number for N
    const result = countValidPermutations(N);

    // Ensure the result is formatted as required
    return result.toExponential(10).replace('+', '');
}

// Run the test
console.log(permutationOf3SmoothNumbers()); // Expected: "5.5350769703e1512"

My output is now 3.5854924789e25
I’m am really confused and I’m just trying to look for help :slightly_frowning_face:

the test that check if the output is a string is bugged, so now you have time to work on this to make sure that your function works to produce the value

Note - you shouldn’t use code other people wrote.
