https://leetcode.com/explore/featured/card/top-interview-questions-easy/92/array/578/

 

 

 

Given an integer array nums, return true if any value appears at least twice in the array, and return false if every element is distinct.

 

 

class Solution {
    fun containsDuplicate(nums: IntArray): Boolean {
        
        // nums에서 중복제거 된 배열을 정의하고
        var distinctArr = nums.distinct()
        
        // 배열 길이 비교해서 차이가 있으면 true
        if (nums.size != distinctArr.size)  
           return true 
        else 
          return false
        
    }
}
