The subSequence(int start, int end) method of Java StringBuffer class returns the new character sequence from given start index to exclusive end index value of this sequence. If the char value specified by the index is a Observe the below alogirithm to solve this problem in O(n) time. This approach is a tabulated implementation for the Longest Common Subsequence. beginIndex - the begin index, inclusive. System.out.println("subStr: " + str.subSequence(0, 13)); Creative Commons-Attribution-ShareAlike 4.0 (CC-BY-SA 4.0). +1 Note: most of the time "subsequence" means "infinite subsequence" so you have to keep infinitely many of the elements. In solving this I figured I wanted to generate the following pairs of indices in the given order. Can you have ChatGPT 4 "explain" how it generated an answer?

A quick guide to check if the string is a subsequence of another string in java. The longest common subsequence (LCS) is defined as the longest subsequence that is common to all the given sequences, provided that the elements of the subsequence are not required to occupy consecutive positions within the original sequences. Mathematics Stack Exchange is a question and answer site for people studying math at any level and professionals in related fields. a valid subsequence is $(1,3,5,7,9,\ldots)$. Compatibility Version: Java 1.5 and above. Could you explain why the order of terms is preserved if is a strictly increasing map?
