- what does this statement do? `nums[i] *= nums[i - 1] or 1`
To understand this nums[i] *= nums[i - 1] or 1 You have to understand two things: Operator Precedence (refer this Python Operator Precedence) Shorthand operator; Let's break it down: We have this syntax for shorthand operator: a = a + 10 means a += 10 So, var = var * value menas var *= value(or statement) Here, or keyword execute first
- nums[i++]=i; performs differently in java and C? - Stack Overflow
nums[i ++] = nums[i + 1] If the i++ happens before the nums[i + 1], i + 1 will be out of bounds on the last iteration In that case, Java rightly causes an error, and C, because it doesn't do bound-checking, happily trusts the code you wrote That code is logically invalid
- Difference between nums[:] = nums[::-1] and nums = nums[::-1]
The assignment nums[:] = nums[::-1] would be equivalent to write a new reversed list at the same address pointed by nums, because the slice allows to replace part of a list with new contents (although in this case the "part" is the whole list) In this case you are not changing the variable nums, but the data pointed by it This is shown in the
- Understanding return [0,size-1][nums[0] lt;nums[size-1]] in Python
nums[0] < nums[size-1] returns either True or False; when used as a list index, this True False is implicitly converted into 1 or 0 and by that, either size-1 or 0 is picked from the list A clearer way to write it is: return size - 1 if nums[0] < nums[size - 1] else 0
- c++ - What does the code int nums [5] do? - Stack Overflow
int nums[5]; allocates memory for a static array of 5 int values When you then do std::cout << nums;, it is actually calling std::cout operator<<(nums); While std::cout has many << operators defined for many different type types, it does not have an << operator that accepts an int[] array as input
- nums[:] = unique anyone please explain this line of code
The important distinction between nums[:] = unique and nums = unique is that the latter will make nums and unique both refer to the same list object in memory In other words, any subsequent changes to unique will also affect nums Using slice notation instead copies unique to nums, although there are many more readable ways to acheive the same
- Answered: Complete the findMax() method that returns the . . . - bartleby
Complete the findMax() method that returns the largest value in array nums Ex: If array nums contains: 2 4 6 8 10 7 5 3 the findMax() method returns: 10 Note: During development, array nums is filled with 10 pseudo-random integers in main() using the fillRandomly() method with a seed value of 7
- can i not do - if nums [i] == nums [i+]: in python - Stack Overflow
I am new to programming and python (ref to code below) - I am trying to compare the elements in a list to eliminate duplicates in adjacent numbers in the list (so that all numbers in the resulting
