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

Suppose we have a number x. We have a six-faced dice and its faces are numbered from 2 to 7. We want exactly x points from the dice. When we throw the dice the face number will be added up to reach our target. We do not really care about the number of dice rolls, so we just want to know any number of rolls we can make to be able to get exactly x points for them. We are very lucky, so if the probability to get x points with chosen number of rolls is non-zero, we will be ... Read More

Suppose we have a number n. We are going to find three numbers a, b and c, such that a + b + c = n and none of these three numbers are multiple of 3.So, if the input is like n = 233, then the output will be [77, 77, 79]StepsTo solve this, we will follow these steps −if (n - 2) mod 3 is same as 0, then:    return 1, 2, and n - 3 Otherwise    return 1, 1, and n - 2ExampleLet us see the following implementation to get better understanding −#include using namespace std; void solve(int n){    if ((n - 2) % 3 == 0)       cout

Suppose we have a string S with n lowercase letters. A string is called diverse if it has consecutive letters of the English alphabet and each letter occurs exactly once. (letters 'a' and 'z' are not adjacent). We have to check whether it is diverse or not.So, if the input is like S = "fced", then the output will be True.StepsTo solve this, we will follow these steps −sort the array S flag := 1 for initialize i := 1, when i < size of S and flag is non-zero, update (increase i by 1), do:    if S[i] - ...

Suppose we have three numbers y, b and r. There are y yellow ornaments, b blue ornaments and r red ornaments for decoration. A decoration will be beautiful, if the number of blue ornaments used is greater by exactly 1 than the number of yellow ornaments, and the number of red ornaments used is greater by exactly 1 than the number of blue ornaments. We want to choose as many ornaments as possible and also want to make our decoration good. We have to find the maximum number of ornaments used for a beautiful decoration.So, if the input is like ...

Suppose we have a string S with n lowercase English letters. We have to reorder the characters in S, so that "trygub" is not a subsequence of the resulting string.So, if the input is like S = "pintontrygubabc", then the output will be "abbcginnoprttuy".StepsTo solve this, we will follow these steps −sort the array S return SExampleLet us see the following implementation to get better understanding −#include using namespace std; string solve(string S){    sort(S.begin(), S.end());    return S; } int main(){    string S = "pintontrygubabc";    cout

Suppose we have three numbers a, b and c. There are a lemons, b apples and c pears. To make a compote, the fruit ratio will be 1 : 2 : 4. We cannot cut any fruit into pieces. We have to find the maximum total number of lemons, apples and pears from which we can make the compote. If not possible, return 0.So, if the input is like a = 4; b = 7; c = 13, then the output will be 21, because we can use 3 lemons, 6 apples and 12 pears, so the answer is 3 ... Read More

Suppose we have a 2d array of size n x 4. Consider there are n students and their ids are starting from 0 to n-1. Each of them has four scores on English, Geography, Maths and History. In the table, the students will be sorted by decreasing the sum of their scores. If two or more students have the same sum, these students will be sorted by increasing their ids. We have to find the id of student whose id is 0.So, if the input is like10098100100100100100100909990100100986099then the output will be 2StepsTo solve this, we will follow these steps −n ...
