After devoting decades of his life to further our space exploration technologies, he’s finally ready to retire. Being a space enthusiast, the first thing he wants to do is visit n planets p1, p2, …, pn, in this order. He’s currently on planet p0. Milan knows that the distance between planets pi and pi + 1 (for 0 ≤ i < n) is d[i]light years. His spaceship uses 1 tonne of fossil fuels per light year. He starts with a full tank and can fill up his tank at any of the n planets (but he must not run out in between two planets). There’s a huge cost to set up the spaceship for refuelling. Due to financial constraints (he’s not THAT rich), he can fill up his tank at most ktimes. In order to save money and make his spaceship lighter, Milan is looking for the smallest possible fuel tank that enables him to complete his space travel and reach planet pn. What is the smallest tank capacity that enables him to do so?…
- For each of the following problems, you should write your answer as an expression. Do not give the final numeric value. For example, if your answer is the number of 6-permutations of a set with 10 elements, you should write P(10,6) or 10!/4! or 10 × 9 × 8 × 7 × 6 × 5, but not 151200.Ex: Let A1 ={x, y}, A2 ={1, 2}, and A3 ={a, b}, Find A1 × A2, (A1 × A2) × A3, A1 × A2 × A3.B=(1)/(4)e*p slove for e
- sum = 0; for (int i = 1; i< n; i = sum++ || 2*i)Python Programming Lab Dr.D has invented yet another invention: the hateinator. He wants to test it on a group of N people (numbered 1 through N). The hateinator may be used any number of times; to use it once, Dr.D should divide these N people into two groups and press the fire button on the hateinator. We call each such grouping a Doofish set. Afterwards, there will be hatred between each two people who were in different groups. The hatred does not disappear ― any two people that hate each other before the hateinator is used still hate each other afterwards. The hateinator uses a lot of power. Let's denote the number of times it is used by K. Then, it consumes K⋅N units of power. Dr.D cannot afford to use the hateinator if this number exceeds 106. Dr.D has done the math and computed the most evil hatred system: a situation with some M pairs of people who hate each other. You are given these pairs. There must not be any other pair of people who hate each other. Initially, there is no…Using JavaScriptDefine a function getMonth which accepts number from 1 to 12 as an argument and return the descriptive name of the month. For example: getMonth(1) should return January while getMonth(12) returns December, finally getMonth(-1) returns null. Use array or object to define a list of names for the month and refrain from using if statement to check the argument if it's 1, 2, etc.
