Consider a JSON string that looks like this:

$["$Swiggy$",123],$

$["$Swiggy$",227],$

$[\text{'}"$Zomato$",103],$

$["$Zomato$",171],$

$["$Dunzo$",131],$

$[\text{'}"$Zomato$",122],$

$["$Swiggy$",181]$ This string encodes a list of payments made by a person for various delivery services. Each element of the list is a itself a list of two elements the first is the name of the service, and the second is the amount.

Write a function$/$method in JavaScript to take such a string and return the number of services for which this person has never paid an amount of $200$ or more.

For example, if the above string is passed to your code, it should return $2($since this person has never paid $200$ or more for Zomato and Dunzo.$)$ Remember, the input will be passed to you as a string.

In the comments in your code, indicate what is the running time of your program e$.$g$.$ O$($n $^2)$ or O $($n log$($n$)).$ You get bonus points if your program has a average running time of $0($n $*$ log$($n$))$ or O$($n$)$
