class Solution {
public boolean containsDuplicate(int[] nums) {
// Initialize a variable to store the result
boolean result = false;
// Sort the array of numbers
Arrays.sort(nums);
// Iterate through the sorted array
for (int i = 0; i < nums.length - 1; i++) {
// Check if the current number is equal to the next number
if (nums[i] == nums[i + 1]) {
result = true; // If duplicate found, set result to true
return result; // Return true as soon as a duplicate is found
}
}
// If no duplicates found, return the initial value of result (false)
return result;
}
}
