Merge two sorted arrays
Merge two nondecreasing arrays into one nondecreasing array, preserving duplicates. Inputs are valid JSON and must not be modified unless the algorithm uses a local copy. This exercise probes typed data modeling, boundary handling, and algorithm selection.
Input
One JSON value: { left: number[]; right: number[] }. See the sample for its exact shape.
Output
One compact JSON value of type number[]. Strings include JSON quotes; arrays preserve the specified order.
Constraints
Array/string lengths are 0 to 10000 unless stated otherwise. Numbers are integers in [-1000000,1000000]; all computed results fit the safe integer range.
Example
Input
{"left":[1,3,5],"right":[2,4]}Output
[1,2,3,4,5]
Example 2 input
{"left":[-5,0],"right":[-4,9]}Output
[-5,-4,0,9]
Checks a boundary or contrasting case beyond the public examples.
Public test cases (2)
Input
{"left":[1,3,5],"right":[2,4]}Expected output
[1,2,3,4,5]
Input
{"left":[],"right":[]}Expected output
[]
Hints (2)
- Start with the required output order and the empty-input behavior.
- Advance whichever input currently has the smaller value
