Ques 3: What is the problem with this block of code? What is the fix?

Re: Thread For Nairaland Algorithm Questions by Karleb(m): 6:53pm On Jan 23, 2021 |
cixak95211: I've not run the code but from what I see. Case 0 returns nothing. The switch statement will get stucked there. Solution, let case 0 return something. case amount > 5000 && amount <= 50000: I doubt if that is a valid case statement. Javascript will get confused at this stage. The logic should be wrapped around a parenthesis since it involves comparison. |

cixak95211: I agree with not using the additional variable 'temp' on line 42. As for line 23, the redundancy is intentional. As for the website for 20k guys, I reserve my comments - for now. |

Re: Thread For Nairaland Algorithm Questions by cixak95211: 7:21pm On Jan 23, 2021 |
Karleb: Case 0 returns 0. If you look well, you'll see the cases are stacked which is a valid switch expression Parenthesis are redundant. A smart code editor, once again, will remove the parentheses if you add it. Prettier will also remove it. Try again. |

Question, implement the doubly linked list data structure. The implementation should be within a class. |
Re: Thread For Nairaland Algorithm Questions by naijasensei: 8:36pm On Jan 23, 2021 |
cixak95211: From the way switch statements work, the expression within 'switch(expression)' is evaluated only once. That is this arrow function will always return either 0 (whenever amount is zero, or amount is undefined) or 50 for all other values because it ignores the comparison expressions in the two case statements following the first one. There are two possible solutions I can think of: 1. Use an if...else if...else construct. 2. Make the expression within 'switch(expr)' to always evaluate to true, then check your expressions within your case statements. const calculateFee = (amount) => { switch (true) { case amount === 0: case amount === undefined: return 0; case (amount > 0 && amount <= 5000): return 10; case (amount > 5000 && amount <= 50000): return 25; default: return 50; } }; const calculateFeeAlt = amount => { if (amount === 0 || amount === undefined) { return 0; } else if (amount > 0 && amount <= 5000) { return 10; } else if (amount > 5000 && amount <= 50000) { return 25; } else { return 50; } };

@naijasensei: Nailed it!!!! However case amount === 0: case amount === undefined: can be better rewritten as case !amount since ! will evaluate the same for falsey, null, zero and undefined same goes for amount === 0 || amount === undefined. |

Shouldn't there be a standard algorithm syntax that explains the problem well? If there isn't then this threads name is bogus. |

Exercise Write a pagination function. This function will convert a 1 dimensional array into a paginated 2 dimensional array. It will take 2 arguments. The first argument is the array to be paginated and the second one is the number of elements per pagination. Examples list=[1,2,3,4,5,6,7,8,9,10] paginate(list, 5) should return [[1,2,3,4,5], [6,7,8,9,10]] paginate(list,2) should return [[1,2], [3,4], [5,6], [7,8], [9,10]] paginate(list, 3) should return [[1,2,3], [4,5,6], [7,8,9], [10]] |

You are given an array and asked to find the element in the array that appears k times. eg arr = {1, 2, 2, 3, 3,3,4,4,4,4} fun = foo(arr, k) k = 2 ans = 2 |

Deicide: Hmm, if I'm to solve this First attempt: Get the unique numbers loop through it get the count of each number Append it to a list /print it out if the count = 2 |
Re: Thread For Nairaland Algorithm Questions by Deicide: 1:06am On Jul 04, 2021 |
JFOD:Ok let's see implementation |
Re: Thread For Nairaland Algorithm Questions by JFOD: 1:18am On Jul 04, 2021 |
Deicide: I'll make use of python (it's easy to get the unique numbers using set) I'm assuming, list will be passed

Re: Thread For Nairaland Algorithm Questions by Deicide: 1:49pm On Jul 04, 2021 |
JFOD:did you test this code? am getting error for unique_num = {lst} unhashable type. though the solutions is correct. but then answer wouldn't be unique cause I have to remove {} |
Re: Thread For Nairaland Algorithm Questions by JFOD: 2:16pm On Jul 04, 2021 |
Deicide: I did not test the code. how to fix it #this will convert the list to set (set doesn't #allow duplicate values, so it will only have #unique numbers) unique_num = set(lst) |
