Is there a way to check subsequence exists in a list?

Is there a way to check subsequence exists in a list?

Is there a way to have a function that checks for subsequence such that the following returns true? e.g. a function call x_in_y (): Maybe something from itertools or operator?

How to find if first string is subsequence of second?

Given two strings, find if first string is a subsequence of second. Given two strings str1 and str2, find if str1 is a subsequence of str2. A subsequence is a sequence that can be derived from another sequence by deleting some elements without changing the order of the remaining elements (source: wiki).

How is a subsequence derived from a sequence?

A subsequence is a sequence that can be derived from another sequence by deleting some elements without changing the order of the remaining elements (source: wiki). Expected time complexity is linear.

How to find the issubsequence of a string?

$t = isSubSequence ($str1, $str2, $m, $n) ? Time Complexity of both implementations above is O (n) where n is the length of str2. This article is contributed by Sachin Gupta.

How to find the sum of all subsets of an array?

Given an array of N positive integers write an efficient function to find the sum of all those integers which can be expressed as the sum of at least one subset of the given array i.e. calculate total sum of each subset whose sum is distinct using only O (sum) extra space.

How to find minimal length subsequence that contains all?

Now, take two indexes, begin and end and iterate them through the array the following way: initialize cnt and begin as 0, end as -1 (to get 0 after first increment). Then while possible perform follows: 2.1. increment end. If end already is the end of array, then break. If cur [array [end]] is zero, increment cnt. Increment cur [array [end]].

Is there a subsequence that contains all unique elements?

If bestLength < numUnique then there is no subsequence containing all unique elements. The algorithm assumes that the elements are positive numbers and that the maximal element is less than the length of the sequence.
