Hi. i learned lots of things . thank you. also thanks for choose js .

[@khanhvu1200]

for the array chunks solution, the question is a bit confusing since the first example returns the last sub array when the sub array length is smaller than the size required, and the second example does not return the last sub array when the sub array length is smaller than the size required. So if we assume that the last sub array will only be returned if its length is the same with the size required, we should have some code like this to cover that edge case: const splitArrToChunk = (arr, size) => { let chunkSizeArr = []; let startingIndex = 0; let subChunkArr = []; for (let i = 0; i < arr.length; i++) { if (subChunkArr.length === size) { chunkSizeArr.push(subChunkArr); subChunkArr = []; } subChunkArr.push(arr[i]); if (i === arr.length - 1 && subChunkArr.length === size) { chunkSizeArr.push(subChunkArr); } } return chunkSizeArr; }; // Testing const startingArr = [0, 1, 2, 4, 5, 6, 9]; console.log(splitArrToChunk(startingArr, 3)); console.log(splitArrToChunk(startingArr, 2)); console.log(splitArrToChunk(startingArr, 1));

I always tell the kids when they ask me how to get started that this is the first thing to learn but they never listen to me

[@envygamer]

One question On Reverse Integer as per the MDN in the parseInt method the leading zero will be ignored If the reverse string is '01234' in that case the algo will fail *How can we handle that situation* EDIT1: Can use of *Number()* help instead of *parseInt()*

[@PumpkinEater6699]

Reverse integer question will have input as an integer.. 0123 is not a valid integer

[@envygamer]

@@PumpkinEater6699 But '0' is still a valid Number, I understand that at the bit level, it will return 0 as well, However, I think there might be an edge case where 0 is deliberately given as a leading number. I think having a flag for catching that 0 at the beginning and then adding it back at the end should be a neat trick. I mean @huxnwebdev might share his 2 cents on this

There is a typo at 5:02:23, corrected code, removeEdge ( vertex1, vertex2 ) { if ( this.adjacencyList [ vertex1 ] && this.adjacencyList [ vertex2 ] ) { this.adjacencyList [ vertex1 ] = this.adjacencyList [ vertex1 ].filter( v => v !== vertex2 ); this.adjacencyList [ vertex2 ] = this.adjacencyList [ vertex2 ].filter( v => v !== vertex1 ); return true; } return false; } From the vertex1 .filter filters the vertex1 array and replaces the original vertex1 array excluding vertex2 value. similarly, From the vertex2 array vertex1 value is removed. This removes the connection between vertex1 & vertex2, leaving vertex1 connection only with c , A [ " C " ] & vertex2 connection only with c , B [ " C " ].

Can you please clarify why we are doing Divide and Conquer at 31:00 and not just accessing by the Array[0] ? I am asking because I am a beginner.

[@IlyesCodes]

Accessing the array item by item is O(n) times, meaning going through the items proportionally to the maximum of input size, however with O(log n) we are accessing the items proportionally to the logarithm of input size. log grows slower than constant time
