Sorry, your code does not pass. Don’t give up.

After your nested for loop, you should declare a temp variable

const selectionSort = (array) => {
for (let i = 0; i < array.length; i++) {
let minIndex = i;

for (let j = i + 1; j < array.length; j++) {
    let temp;
  console.log(array, array[j], array[minIndex]);
  if (array[j] < array[minIndex]) {
    minIndex = j;
   temp=array[i];
    array[i]=array[minIndex];
    array[minIndex]=temp;

  }
}

}
}

Hi @surafel1

Delete this code as it will not pass the tests.

Your temp variable needs to be declared with a certain keyword. Look at your previous code to guide which keyword to use.

Also your code needs to go after the second for loop.

Happy coding

still not passing the code eventhough i removed let temp.put my after the nested for loop.here is the code const selectionSort = (array) => {
for (let i = 0; i < array.length; i++) {
let minIndex = i;
for (let j = i + 1; j < array.length; j++) {
console.log(array, array[j], array[minIndex])
if (array[j] < array[minIndex]) {
minIndex = j;
}
}
if (minIndex !== i) {
let temp = array[i];
array[i] = array[minIndex];
array[minIndex] = temp;
}
}
}

Hi @surafel1

Delete this line of code, it was not asked for in the instructions.

Then delete one of the curly braces from the end of your code.

You’ll have to use the const keyword, as this is how the other variables were declared.

Happy coding
