(Aug 19 -- Aug 23) Sum and prefix sums: For many problems where data is stored in an 1D-array, computing the sum or prefix (or postfix) sums can reduce the complexity from O (n^2) to O (n). For some problems, it is necessary to store these sums … WebDivisibility Of Strings As part of an assignment, a student is required to find whether a given string s is divisible by string t. If it is divisible, the student needs to find the length of the smallest string x such that if x is concatenated any number of times, we get both s and t. If this is not possible, the student needs to print -1.
