查找关于第二个序列的值和这些最接近匹配的位置(索引)的序列的按元素最接近的匹配

function findClosestMatches(sequence1, sequence2) {
  let closestMatches = [];

  for (let i = 0; i < sequence2.length; i++) {
    let closestValue = null;
    let closestIndex = null;

    for (let j = 0; j < sequence1.length; j++) {
      let diff = Math.abs(sequence2[i] - sequence1[j]);

      if (closestValue === null || diff < Math.abs(sequence2[i] - closestValue)) {
        closestValue = sequence1[j];
        closestIndex = j;
      }
    }

    closestMatches.push({
      value: closestValue,
      index: closestIndex
    });
  }

  return closestMatches;
}

// 示例用法
let sequence1 = [1, 3, 5, 7, 9];
let sequence2 = [2, 4, 6, 8, 10];

let closestMatches = findClosestMatches(sequence1, sequence2);
console.log(closestMatches);
