    Here is my O(N) c++ solution, you can watch the explanation here : https://youtu.be/8p9yuqSv4ek

    int equalizeArray(vector<int> arr) {
    map<int, int>mp;
    int mx = 0;
    for(int el: arr) {
        mp[el]++;
        if(mp[el]>mx) mx = mp[el];
    }
    return arr.size() - mx;
}

    Python

    from collections import Counter

def equalizeArray(arr):
   return len(arr) - max(Counter(arr).values(), default=0)

    Solutions in Python using collectinos lib:

    def equalizeArray(arr):
    ctr = Counter(arr)
    dct = dict(ctr.items())
    max_val = max(dct.values())
    
    return len(arr) - max_val

    l=len(arr)
    d_arr={}
    for i in arr:
        if i in d_arr:
            d_arr[i]=d_arr[i]+1 
        else:
            d_arr[i]=1 
    ma=0
    ans=list()
    for i in arr:
        if d_arr[i]>ma:
            ma=d_arr[i] 
    return l-ma

    Here is my one line Python solution utilizing a Counter object!

    def equalizeArray(arr):
    return sum(Counter(arr).values()) - max(Counter(arr).values())
