WebOct 11, 2024 · To check the status of visited elements create a array of size n. Run a loop from index 0 to n and check if (visited [i]==1) then skip that element. Otherwise create a variable count = 1 to keep the count of frequency. Run a loop from index i+1 to n Check if (arr [i]==arr [j]), then increment the count by 1 and set visited [j]=1. WebMar 8, 2024 · Finding the non repeating element in an array can be done in 2 different ways. Method 1: Use two loops, one for the current element and the other to check if the element is already present in the array or not. Method 2: Traverse the array and insert the array elements and their number of occurences in the hash table. WebGiven an array nums containing n distinct numbers in the range [0, n], return the only number in the range that is missing from the array. Example 1: Input: nums = [3,0,1] Output: 2 Explanation: n = 3 since there are 3 numbers, so all numbers are in the range [0,3]. 2 is the missing number in the range since it does not appear in nums. Example 2: secondary dns services
