Subsequence Problem is one of themost common algorithm problem, which is not easy to figure out. First of all, the subsequence problem itself is more difficult than those for substring and subarray, since the former needs to deal with discontinuous sequence, while the latter two are continuous....

var subArray = numbers[1..4]; // Creates a range from index 1 to 3 (inclusive) In this example,numbers[1..4]creates a sub-array that includes elements at indices 1, 2, and 3 from thenumbersarray. Best Regards, Jiale If the answer is the right solution, please click "Accept Answer...
Explore what is Merge Sort Algorithm in data structure. Read on to know how does it work, its implementation, advantages and disadvantages of Merge sort.
In this step, the sorting of the elements will be done. But in some cases, the algorithm performs in a way that divides the element more. In this example, the sub-arrays have only two elements each. That is also low in several terms.But some algorithms divide it further into small par...
1) Select an array element. This element refers to as a pivot. 2) Divide the unsorted element array into two arrays with values lower than the first subarray’s pivot. In the second subarray, all elements with values above the pivot (equal values can go anyway). This step is called the...
The above step is repeated for each subarray of smaller values as well as done separately for the subarray with greater values. This is repeated until the entire array is sorted.
Given a non-empty 2D matrixmatrixand an integerk, find the max sum of a rectangle in thematrixsuch that its sum is no larger thank. Example: Input: matrix =[[1,0,1],[0,-2,3]], k =2 Output:2 Explanation: Because the sum of rectangle[[0, 1], [-2, 3]]is 2, ...
In case of multiple appearances to choose from, take the last occurence of the unpaired character. Notes: A wide range of characters is used, and some of them may not render properly in your browser. Your solution should be linear in terms of string length to pass the last test. ...
When we look back to the file after sometime, we can easily recall what a certain variable, function, or class represents. Developers should avoid choosing inappropriate names.The naming convention in Python is slightly messy, but there are certain conventions that we can follow easily. Let's ...
