Lecture22: All about Char Arrays, Strings & solving LeetCode Questions

In this Video, we are going to learn about char arrays, strings and solve the following questions:
- Length of String
- Reverse a String
- Check Palindrome
- Valid Palindrome
- Reverse words
- Maximum occurring character
- Remove all occurrences of substring
- Remove all adjacent duplicates
- String Compression

There is a lot to learn, Keep in mind “ Mnn boot karega k chor yrr apne se nahi yoga ya maza nahi para, Just ask 1 question “ Why I started ? “
