Suppose we have two numbers a and b. Amal always sets TV volume to 'b' value. But someday Bimal has changed it to 'a' value. The remote has six buttons (-5, -2, -1, 1, 2, 5) using them we can increase or decrease the volume by 1, 2 or 5. Volume can be very large but not negative. We have to count the number of buttons Amal needs to press at minimum to get the volume same as b.So, if the input is like a = 5; b = 14, then the output will be 3, because press +5 to ... Read More

Suppose we have a number n. We have to find an array A of size n. There are n tables and each table has 4 chairs. Chairs are numbered from 1 to 4n. It is known that two kids who sit on chairs with numbers a and b (a != b) will indulge if −gcd(a, b) = 1 or, a divides b or b divides a.We want to seat the kids so there are no 2 of the kid that can indulge. More formally. We have to find the chair association.So, if the input is like n = 4, then ... Read More

Suppose we have two coordinates (x1, y1) and (x2, y2). A rabbit is pulling food box. He is attached with a rope with only 1 unit sized rope. Rabbit will pull the box to where it is standing before moving out of the way in the same direction by 1 unit. Rabbit can move 1 unit to the right, left, up, or down without pulling the box. In this case, it is not necessary for it to be in exactly 1 unit away from the box. If he wants to pull the box again, it must go to a point ... Read More

Suppose we have two numbers n and k. In a party there are n invited friends. Amal wants to make invitations in the form of origami. For each invitation, he needs two red papers, five green papers, and eight blue papers. There are infinite number of notebooks of each color, but each notebook consists of only one color with k papers. We have to find the minimum number of notebooks that Amal needs to buy to invite all n of his friends.So, if the input is like n = 3; k = 5, then the output will be 10, because ... Read More

Suppose we have a lowercase string S with n characters. We have to find two non-empty substrings P and Q, such that −Both P and Q are subsequences of SFor each index i, S[i] belong to exactly one of P and Q.P is lexicographically minimum as possible.So, if the input is like S = "thelightsaber", then the output will be 10, because we need 2 red notebooks, 3 green notebooks, and 5 blue notebooks.StepsTo solve this, we will follow these steps −c := S sort the array c a := position of (c[0]) in S delete c from S print ...

Suppose we have a number n, two arrays A and B of size k1 and k2 respectively. Amal and Bimal are playing interesting card game. There are n cards, numbered 1 to n. Initially the cards are distributed between them. The game goes as follows: on each turn, each player takes one of their cards (whichever they want) and puts on the table, so that the other player doesn't see which card they chose. Then, both cards are revealed, and the player, whose card number is larger, takes both cards in his hand. Every card may be played any amount ... Read More

Suppose we have an array A with n elements. There are n numbers written on a board. Amal and Bimal are playing a turn based game. In each turn, they select a number and remove it from board. Amal plays first. Amal wants to minimize the last number that he would left on the board, and Bimal wants to maximize it. We have to find the number which will remain on the board.So, if the input is like A = [2, 1, 3], then the output will be 2, because Amal will remove 3, Bimal will remove 1, so the ... Read More

Suppose we have a number n. In a game, every character has four different health points (HP). The categories are as follows −Category A : If HP is in the form (4n + 1)Category B : If HP is in the form (4n + 3)Category C : If HP is in the form (4n + 2)Category D : If HP is in the form 4nThese 4 categories ordered from highest to lowest as A > B > C > D. So, category A is the highest and category D is the lowest. While playing the game, players can increase the ... Read More

Suppose we have a string S with two kinds of letters 'S' and 'F'. If S[i] is 'S' we are at Seattle on ith day, and if it is 'F' we are at Florida. We have to check whether we flew more times from Seattle to Florida than Florida to Seattle.So, if the input is like S = "SSFFSFFSFF", then the output will be True.StepsTo solve this, we will follow these steps −n := size of S if S[0] is same as 'S' and S[n - 1] is same as 'F', then:    return true Otherwise    return falseExampleLet us ...

Suppose we have two numbers l and r. We have to find such pair (x, y), such that l
