And remember this is only about Whole Numbers (1, 2, 3, ... etc), not fractions or negative numbers. So don't say "I could multiply ½ times 6 to get 3", OK?Examples:3 = 1 × 3 (the only factors are 1 and 3) Prime 6 = 1 × 6 6 = 2 × 3 (the factors are 1, ...
What is the difference between prime numbers and composite numbers?Aprimenumber is anumerical digitthat isgreater than 1and that you can only divide it by 1and by itself, the remainder will be 0. Example:7can only bedividingby7or 1.(7/7=1)and (7/1=7)A composite numberis a number...
The number 2 is theonly prime that is even. All other even numbers have 2 as a factor and so they are composite numbers. Twin primesare pairs of primes whose difference is 2. (3, 5), (5, 7) and (11, 13) are examples of twin primes. ...
However, array A cannot be divided into four blocks, (1, 2, 3), (4, 3, 4), (1, 2, 3) and (4, 6, 2), because the (1, 2, 3) blocks do not contain a peak. Notice in particular that the (4, 3, 4) block contains two peaks: A[3] and A[5]. The maximum number of...
