AnswersGiven the arraylist<meals> input, find the number of dishes with unique ingredients.
class meals{ String cuisine; ArrayList<String> dish = new ArrayList<String>(); meals(String s, String[] arr){ cuisine = s; for(String i:arr){ dish.add(i); } } }
Example:
- venkataratnamkumar7777 in United States
Input: [
{
"cuisine" : "American",
"dish" : ["lettuce", "cheese", "olives", "tomato"]
},
{
"cuisine" : "Mexican",
"dish" : ["lettuce", "cheese", "pepper", "tomato"]
},
{
"cuisine" : "French",
"dish" : ["lettuce", "cheese", "pepper", "tomato"]
},
{
"cuisine" : "Continental",
"dish" : ["lettuce", "cheese", "olives", "tomato"]
},
]
Output: 2
Because there are two unique ingredient-dishes; {Mexican, French} and {American, Continental}.
I have tried different methods, but could not get to the solution. Thank you!| Report Duplicate | Flag | PURGE
