WebOct 8, 2016 · The goal of this function is to count the number of steps it takes a number to get to 1 after performing operations. The number you put into the function is divided by 2 if the number is even, and tripled and increased by 1 if the number is odd. These operations are performed on the number until it reaches one. WebFeb 18, 2024 · The 1 + collatz (...) is taking the step you just took, represented by the 1, and then adding the number of steps (calculated recursively) that the resulting number will take. For example, collatz (5) will result in the recursive method returning 1 + collatz (16) + collatz (8) + collatz (4) + collatz (2) + collatz (1) or, 1 + 1 + 1 + 1 + 1 + 0 = 5

WebFeb 2, 2024 · The Collatz sequence is formed by starting at a given integer number and continually: Dividing the previous number by 2 if it's even; or. Multiplying the previous number by 3 and adding 1 if it's odd. The Collatz conjecture states that this sequence eventually reaches the value 1.
