For a = 2 and b = 7, the output should be rangeBitCount(a, b) = 11. Given a = 2 and b = 7 the array is: [2, 3, 4, 5, 6, 7]. Converting the numbers to binary, we get [10, 11, 100, 101, 110, 111], which contains 1 + 2 + 1 + 2 + 2 + 3 = 11 1s. Input/Output [execution time limit] 0.5 seconds (cpp) [input] integer a Guaranteed constraints: 0 ≤ a ≤ b. [input] integer b Guaranteed constraints: a ≤ b ≤ ..

You are given an array of up to four non-negative integers, each less than 256. Your task is to pack these integers into one number M in the following way: The first element of the array occupies the first 8 bits of M; The second element occupies next 8 bits, and so on. Return the obtained integer M. Note: the phrase "first bits of M" refers to the least significant bits of M - the right-most bi..

In order to stop the Mad Coder evil genius you need to decipher the encrypted message he sent to his minions. The message contains several numbers that, when typed into a supercomputer, will launch a missile into the sky blocking out the sun, and making all the people on Earth grumpy and sad. You figured out that some numbers have a modified single digit in their binary representation. More spec..

Remove extra white-spaces from the given string. Example For input = " abc a aa a a ", the output should beformatString(input) = "abc a aa a a". code>> string formatString(string i) { return i.Split(new char[] { ' ' }, StringSplitOptions.RemoveEmptyEntries).Aggregate((l,r)=> l+" "+r);} 문자열 처리에 C++은 최악...

Consider the Fibonacci sequence: 0 1 1 2 3 5 8 13 21 ... We can see that 7 is the smallest 0-based index k for which F(k) has exactly 2 decimal digits.What is the smallest index k for which F(k) has exactly n decimal digits? Example For n = 1, the output should befibonacciIndex(n) = 0;For n = 2, the output should befibonacciIndex(n) = 7. code>> int fibonacciIndex(int n) {if (n == 1) return 0;int..

You just bought a public transit card that allows you to ride the Metro for a certain number of days. Here is how it works: upon first receiving the card, the system allocates you a 31-day pass, which equals the number of days in January. The second time you pay for the card, your pass is extended by 28 days, i.e. the number of days in February (note that leap years are not considered), and so o..

Once Mary heard a famous song, and a line from it stuck in her head. That line was "Will you still love me when I'm no longer young and beautiful?". Mary believes that a person is loved if and only if he/she is both young and beautiful, but this is quite a depressing thought, so she wants to put her belief to the test. Knowing whether a person is young, beautiful and loved, find out if they cont..

In tennis, the winner of a set is based on how many games each player wins. The first player to win 6 games is declared the winner unless their opponent had already won 5 games, in which case the set continues until one of the players has won 7 games. Given two integers score1 and score2, your task is to determine if it is possible for a tennis set to be finished with a final score of score1 : s..

Consider an arithmetic expression of the form a#b=c. Check whether it is possible to replace # with one of the four signs: +, -, * or / to obtain a correct expression. Example For a = 2, b = 3 and c = 5, the output should bearithmeticExpression(a, b, c) = true. We can replace # with a + to obtain 2 + 3 = 5, so the answer is true. For a = 8, b = 2 and c = 4, the output should bearithmeticExpressi..

Given integers a and b, determine whether the following pseudocode results in an infinite loop while a is not equal to b do increase a by 1 decrease b by 1Assume that the program is executed on a virtual machine which can store arbitrary long numbers and execute forever. Example For a = 2 and b = 6, the output should beisInfiniteProcess(a, b) = false;For a = 2 and b = 3, the output should beisIn..
