The good and widely used way to define the hash of a string s of length n ishash(s)=s[0]+s[1]⋅p+s[2]⋅p2+...+s[n−1]⋅pn−1modm=n−1∑i=0s[i]⋅pimodm,where p and m are some chosen, positive numbers.It is called a polynomial rolling hash function. generate link and share the link here. Given an array A of non-negative integers, the array is squareful if for every pair of adjacent elements, their sum is a perfect square.. Return the number of permutations of A that are squareful. A number is considered perfect if its digits sum up to exactly 10. Please write comments if you find anything incorrect, or you want to share more information about the topic discussed above.
