你应该简单地将 i < A.length && j < B.length 作为循环条件进行检查。
这是你更新后的代码:
const mergeSort = { solve: function (A) { return this.mergeSortFunction(A); }, mergeTwoSortedArrays: function (A, B) { let i = 0; let j = 0; let k = 0; let C = []; while (i < A.length && j < B.length) { if (A[i] < B[j]) { C[k] = A[i]; i++; k++; } else { C[k] = B[j]; j++; k++; } } while (j < B.length) { C[k] = B[j]; k++; j++; } while (i < A.length) { C[k] = A[i]; k++; i++; } return C; }, mergeSortFunction: function (a) { let n = a.length; if (n <= 1) return a; let c = Array.from({ length: Math.floor(n / 2) }, (_, i) => a[i]); let d = Array.from({ length: n - c.length }, (_, i) => a[c.length + i]); return this.mergeTwoSortedArrays(this.mergeSortFunction(c), this.mergeSortFunction(d)); } }; // 示例 const inputArray = [38, 27, 43, 3, 9, 82, 10]; const sortedArray = mergeSort.solve(inputArray); console.log(sortedArray); // 输出:[3, 9, 10, 27, 38, 43, 82]
