In this post, we will see about how to count subtrees with Sum equal to target in binary tree Problem Given a Binary tree and an integer. You need to find the number of subtrees having the sum of all of its nodes equal to given Integer, that is, Target sum. Solution For solving ...
Given an arrayarrarrof lengthNN, find the sum of count of unique values in a subset for every subset ofarrarr, modulo10+7109+7. I can see that the result depends only on frequency of distinct values, and seems like some combinatorial trick, it's a made up question but seems standard,...
Suppose we have a list of numbers called nums and another value k, we have to find the number of subsets in the list that sum up to k. If the answer is very large then mod this with 10^9 + 7 So, if the input is like nums = [2, 3, 4, 5, 7] k = 7, then the output...

On this problem given a stringswe need to return the sum ofcountUniqueChars(t)wheretis a substring ofs. Notice that some substrings can be repeated so on this case you have to count the repeated ones too. Since the answer can be very large, return the answer modulo10 ^ 9 + 7. ...
Then we check if we can distinguish two subsets S0 and S1, as shown in Eqs. (17) and (18), for some 1 ≤ M ≤ N2. Further details have been given in Algorithm 2. Let us call this the amplitude test. After passing this test we have a unitary of the form E†Q ...
with this we derive a bound on the CS-count of arbitrary multi-qubit unitaries. Analysing the channel representation of the generating set elements, we infer{\mathcal {J}}_n^{CS}\subset {\mathcal {J}}_n^T, where{\mathcal {J}}_n^{CS}and{\mathcal {J}}_n^Tare the set of ...
