    PYTHON :

    def isValid(s):
    # Write your code here
    a = Counter(s)
    set1 = set(s)
    lst = sorted(list(a[p] for p in set1))
    lst1 = list(i-lst[0] for i in lst)
    
    if sum(lst1)==1 or sum(lst1)==0 or sum(lst1)==(len(lst1)-1)*lst1[-1]:
        return 'YES'
    else:
        return 'NO'
