计算数组中每个元素与其他元素的差异百分比

Question

I have an array const arr = [1,2,3,6,7]. I want to calculate the percentage of difference of each element with others in the array. For example: 1 is 100% of arr[0], 50% of arr[1], 33.33% of arr[2], 16.66% of arr[3]; 2 is 200% of arr[0], 100% of arr[1], 66.66% of arr[2], 33.33% of arr[3] etc... Can someone help me solve this problem or at least give a hint? I'm very glad your any answers.

I am just practicing my JavaScript so took your project on as a little test.

I have developed a solution below that works. Feel free to ask me questions:)

const inputFunc = (num) => {

 const arr = [1,2,3,4,5,6,7]
 let newArr = []
 for(let i = 1; i < arr.length + 1; i++){
  let result = num / i * 100
  if(String(result).length >= 4){
   newArr.push(`${result.toFixed(2)}%`)
  }
  else{
   newArr.push(`${result}%`)
  }
 }
 for(let i = 0; i < newArr.length; i++){
  console.log(newArr[i])
 }
}
inputFunc(1)
