Json validator
Here is Expression Evaluation problem example (which is similar to json evaluation but in a different context)
Json Validator Write a class based C++ program to validate a Json string, it has only {}, [], and string key and string value. Your program gets a string from the user and uses a pointer-based stack to determine whether its parentheses are properly balanced/matched. Size of characters is less than 100. Assume that operator will enter only [.], {}, :, a-z, ",",". Whitespace is acceptable too. You do not need to check if input Json string has a duplicate key or not. Note that this problem is simplified version of Expression Evaluation problem (pg. 128 and 129), where two stacks are used for operators and operand. A few examples are given below. Enter a json string: { "a":""} True Enter a string: { "a":"b", "x":"y"} True Enter a string: { "a":"b", "x":"y" False Enter a string: { "a": "b" "x": "y" } False Enter a string: { "a":"b", "x": [ { "r":"a" }] } True Enter a string: { "a":"b", "x": [ { "r":"a", "a":"b" }]} True Enter a string: {"x":[{' "a":"b"}],"a":"b","t":[ True "a", "a":"b"}]} Dijkstra's Two-Stack Algorithm for Expression Evaluation public class Evaluate { public static void main(String[] args) { StackStep by Step Solution
