1 = 20, 2 = 21, 3 = 20 + 21, ....

- A concept related, but not identical, to an algorithm is the idea of a heuristic. Read about heuristics and identify the differences between the two. Describe a heuristic for obtaining an approximate answer to the sum of two three-digit numbers and show how this "addition heuristic" differs from the addition algorithm of Figure 1.2.State the principle of mathematical induction and prove by mathematical induction that for all positive integers n. 1+2+3+........+n = n(n+1)/2Show that if n is an integer and is odd, then n is even using A proof by contraposition A proof by contradiction
- proof that if x is an integer and x3 + 11 is odd, then x is even using a proof by contradiction.Correct answer will be upvoted else downvoted. Computer science. stage is a succession of n integers from 1 to n, in which every one of the numbers happen precisely once. For instance, [1], [3,5,2,1,4], [1,3,2] are stages, and [2,3,2], [4,3,1], [0] are not. Polycarp was given four integers n, l, r (1≤l≤r≤n) and s (1≤s≤n(n+1)2) and requested to find a stage p of numbers from 1 to n that fulfills the accompanying condition: s=pl+pl+1+… +pr. For instance, for n=5, l=3, r=5, and s=8, the accompanying stages are reasonable (not all choices are recorded): p=[3,4,5,2,1]; p=[5,2,4,3,1]; p=[5,2,1,3,4]. However, for instance, there is no change reasonable for the condition above for n=4, l=1, r=1, and s=5. Help Polycarp, for the given n, l, r, and s, find a stage of numbers from 1 to n that fits the condition above. In case there are a few appropriate changes, print any of them. Input The primary line contains a solitary integer t (1≤t≤500). Then, at that point,…Use the mathmetical induction to proove that 3^2n-1 is divisible by 4 whenever n is positive intger
- Use the Principle of Mathematical Induction to verify that 2 divides n2 + n for all positive integers n.Write an algorithm, called Decomposition_Powers_Three, which produces thedecomposition of each integer using powers of 3, namely 1, 3, 9, 27, and 81, and the +and – operators. Each power of 3 should appear at most once in the decomposition.Examples: 1 = 1 2 = 3 – 1 3 = 3 4 = 3 + 1 7 = 9 – 3 + 1 14 = 27 – 9 – 3 – 1 43 = 81 – 27 – 9 – 3 + 1 121 = 81 + 27 + 9 + 3 + 1One of the famous proofs of modern mathematics is Georg Cantor’s demonstration that the set ofrational numbers is enumerable.
