Correct answer will be upvoted else downvoted. Computer science. You are given three positive (more prominent than nothing) integers c, d and x. You need to track down the number of sets of positive integers (a,b) with the end goal that balance c⋅lcm(a,b)−d⋅gcd(a,b)=x holds. Where lcm(a,b) is the most un-normal various of an and b and gcd(a,b) is the best normal divisor of an and b. Input The primary line contains one integer t (1≤t≤104) — the number of experiments. Each experiment comprises of one line containing three integer c, d and x (1≤c,d,x≤107). Output For each experiment, print one integer — the number of sets (a,b) to such an extent that the above uniformity holds.
For (∃ x)(P(x,b)) Would an example of this being true if the domain was all the Avengers and x was green skin, then "b" being the Hulk would make this true. Am example of this being false would be: If the domain was all integers and x was positive, even integers and "b" was integers greater than zero.
Correct answer will be upvoted else Multiple Downvoted. Don't submit random answer. Computer science. You have a knapsack with the limit of W. There are likewise n things, the I-th one has weight wi. You need to place a portion of these things into the knapsack so that their all out weight C is half of its size, however (clearly) doesn't surpass it. Officially, C ought to fulfill: ⌈W2⌉≤C≤W. Output the rundown of things you will place into the knapsack or establish that satisfying the conditions is unimaginable. In case there are a few potential arrangements of things fulfilling the conditions, you can output any. Note that you don't need to expand the amount of loads of things in the knapsack. Input Each test contains various experiments. The principal line contains the number of experiments t (1≤t≤104). Depiction of the experiments follows. The main line of each experiment contains integers n and W (1≤n≤200000, 1≤W≤1018). The second line of each experiment…

Computer science. decimal portrayal of x without driving zeroes comprises of a digits; the decimal portrayal of y without driving zeroes comprises of b digits; the decimal portrayal of gcd(x,y) without driving zeroes comprises of c digits. gcd(x,y) indicates the best normal divisor (GCD) of integers x and y. Output x and y. In case there are various replies, output any of them. Input The primary line contains a solitary integer t (1≤t≤285) — the number of testcases. Every one of the following t lines contains three integers a, b and c (1≤a,b≤9, 1≤c≤min(a,b)) — the necessary lengths of the numbers. It very well may be shown that the appropriate response exists for all testcases under the given limitations. Extra requirement on the input: all testcases are unique.

Alex is playing Poker card game. He starts with a deck of N cards, where for each valid (i), the ith card has an integer A¡ written on it. Now the dealer starts dealing the cards one by one in the order from card 1 to card N. Alex wins if at some moment in time, the sum of all the cards dealt so far is between X and Y inclusive; if this never happens, Alex loses. You are now helping Alex to win the game, so without him noticing, you will swap some pairs of cards before the game starts. Develop a python script to find the smallest number of swaps we need so that Alex would win the game, or find that it is impossible to make Alex win. Display a single line containing one integer i.e., the smallest required number of swaps or -1 if Alex cannot win. Input: 5 15 22 10 15 22 4 19 Output: 1
