WebMay 10, 2024 · This makes sense, since if a and b have a common factor then both a+b and a*b are divisible by this common factor, which increases the probability that a+b divides a*b. So let's try to find out more formally when (a,b) is a good pair: Let g=gcd(a,b). Then there exist integers r,s with. a = r * g b = s * g Then . a + b = (r+s)*g a * b = r*s*g^2 WebJul 17, 2024 · k: the integer to divide the pair sum by; Input Format. The first line contains 2 space-separated integers, n and k. The second line contains n space-separated integers describing the values of ar[ ar[0], ar[1], …, ar[n-1]]. Constraints. Output Format. Print the number of (i, j) pairs where i < j and a[i] + a[j] is evenly divisible by k ...
Webmake combinations of pairs (with certain restrictions) assuming no repeated indices, i.e. idx_i != idx_j; assuming (lst[0], lst[1]) is not distinct from (lst[1], lst[0]) filter pairs whose sum equal the target; count the filtered result; Options. itertools is certainly nicer if allowed: WebFeb 8, 2024 · Similarly, you can pair 6, 10, because 6 will give you MOD 2 and 10 will also give you MOD 2. Combining these, you will get a number which is divisible by 4. Finally, you can pair numbers giving MOD 1 and MOD 3. Because the sum of these pairs would be divisible by 4. If you have X many MOD 1 and Y many MOD 3, you can make X * Y …
Web2. Let the divisor be k. 3. Let the total divisible pair count be d. Initialize d to 0. 4. Start a loop which runs with a counter i starting from 0 to n-1. 4.1.1 If arr [i] + arr [j] is wholely divisible by k then increment d by 1. 4.1.2 Repeat step 4.1.1 for all the array elements until loop termination condition is met. WebJun 30, 2024 · Then, for the sum of two numbers to be divisible by K, the sum of their remainders must be a multiple of k (including 0). So, if we keep track of each possible remainder, and make sure that each remainder is matched by its negation mod k, we can see if the pairing is possible. def isPairable (array, k): modK = [0] * k for n in array: modK …
WebNov 21, 2024 · Now we take our target, call it sum and we wish to enumerate the pairs which add to that target. Enumerate the keys of the map. Suppose the key is k. We compute sum-k. Now there are two cases. Case 1: if sum-k == k then check the map to see if the value associated with k is 2 or greater. If it is, then we have a pair (k, k). Output it.
