How do I parse below JSon string to get the value of RESULT & ERROR?
{
    "RESPONSE": [
        {
            "DT": "20210317",
            "I_NO": "1031021",
            "C_NO": "1021",
            "RESULT": "E",
            "DCODE": "2-B1",
            "ERROR": "[AMT] is mandatory."
        }
    ]
}
