2. CLP_Core Java_E2 - Hands-on 2
JSON is a syntax for storing and exchanging data.
JSON rules:
- Data is separated by commas. Curly braces hold objects (name/value pairs), and square brackets hold arrays (values).
- Values can be literals, objects, or arrays.
- Data starts at level 1.
- If a level 1 key has an object as value, the keys in that object are at level 2.
Input Specification:
input1: Stringified JSON object.
Output Specification:
The function should return the deepest level contained in the JSON object.
Example
input1: {"0": { "name": "John"},"1":{"name":"micheal"}}
Output: 2
Explanation:
{
"0": {
"name": "John"
},
"1": {
"name": "micheal"
}
}
The maximum depth level is 2.
Solution:-> JSON Level Count
import java.io.*;
import java.util.*;
public class Main
{
public static int levelCount(String word){
int maxLevel=1;
int curLevel=1;
/*write your code here and return appropriate value*/
char[] arr = word.toCharArray();
for (int i=0;i<arr.length;i++) {
if(arr[i]=='{') {
curLevel++;
if (curLevel>maxLevel) {
maxLevel++;
}
}
else if (arr[i]=='}' ){
curLevel--;
}
}
return maxLevel;
}
public static void main(String[] args)
{
// String word="{\"0\":{\"name\":\"John\"},\"1\":{\"name\":\"micheal\"}}";
String word="{\"0\":{\"name\":\"[John]\"}\",\"1\":{\"name\":\"[micheal]\"}}";
System.out.println(levelCount(word));
}
}
