just a ques,an answer would bee highly appreciated

why don't we just import all the functionalities of the util package at once by using the '*'...
i get confused why people need to import every other package individually

simply cuz 1+1=2
but 97+97!=98

he fistlly converted whole string to lowercase to avoid any complications int the case senstivity and then filtered the string with stream operations ont the basis of freqency of either character

i did the same thing but with for loop,and even tho for loop has less time complexity,it still got timed out,and i dropped this approach
