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
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
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
