how he’s working with frequency array in “Unique characters string” problem
Count Qunique in string
hello @sauzepplin
we have declared 26 size frequency array to store its frequency.
at 0 we are storing frquency of ‘a’
at 1 we are storing frequency of ‘b’
similary other characters frequency.
if at any instant we find a character that is already occurend before(freq[that har] >0) then we return false becuase of repetition
Can we disscus it over meet , this is not making a lot sense to me.
do a dry run on small test case.
am having issue in this part only
…
dry run on these two strings->
s=“bada”
s=“abcd”
not getting it ! not even after drying run it.
ok then first try to solve this problem->
u r given a string and u need to find the frequency of each character of that string.
