Squary Given N integer, is it possible to add at least 1 and at most K elements such that the sum of the squares of all elements in list equals square of sum of the all elements? solution Let $$ a_i $$ or A be the list of the given n elements. Let $$ b_j $$ be the list of the elements to add the `A` list. $$(\sum_{i}a_i
solution
Check a letter appearance
First, check all of the middle letters, which all letters other than the first and last consecutive segment of letters.
If a letter in middle letter appears more than one input string, it is impossible to construct the megatower.

Google Kickstart 2021 Round A Solutions K-Goodness String Problem Charles defines the goodness score of a string as the number of indices ii such that Si≠SN−i+1Si≠SN−i+1 where 1≤i≤N/21≤i≤N/2 (11-indexed). For example, the string CABABC has a goodness score of 22 since S2≠S5S2≠S5 and S3≠S4S3≠S4. Charles gave Ada a string SS of length NN, consisting of uppercase letters and asked her to convert it into a string with a goodness score of KK. In one operation, Ada can change any character in the string to
