Q. Lucky Number
Definition:
● A lucky number is a number whose value is equal to the occurrence of that number in an
array.
○ [2, 2, 3, 3] => 2
● If there is more than one number whose value is equal to the occurrence of that number
in an array, then the lucky number will be the one with the maximum value among all
lucky numbers.
○ [1, 2, 2, 3, 3, 3, 4] => 3
● If there is no number in an array whose value is equal to the occurrence of that number
in the array then the lucky number will be -1.
○ [5] => -1
Implement a function getLuckyNumber(numbers) that takes an array of positive integers as
input and returns the lucky number from the array.
Test Cases:
● getLuckyNumber([2, 2, 3, 3]) => 2
● getLuckyNumber([1, 2, 2, 3, 3, 3, 4]) => 3
● getLuckyNumber([5]) => -1
getLuckyNumber(numbers)
{
// function implementation
// return number whose value is equal to the occurrence of the number in the array
// e.g [2, 2, 3, 3] => lucky number = 2
// in case there are multiple lucky numbers return the maximum lucky number
// e.g [1, 2, 2, 3, 3, 3] => lucky number = 3
// else return -1
// e.g [5] => lucky number = -1
}
