Asked in companies
You are given a string 'STR'. The string contains [a-z] [A-Z] [0-9] [special characters]. You have to find the reverse of the string.
For example:
If the given string is: STR = "abcde". You have to print the string "edcba".
follow up:
Try to solve the problem in O(1) space complexity.
Problem approach
You are given a string ‘S’. You are also given ‘M’ integers in an array ‘A’. You perform ‘M’ operations on this string. The operations are given in an array ‘A’ of size ‘M’.
You perform the operations in the order they appear in the array ‘A’. In the ‘i’th operation, you reverse the substring of ‘S’ from the position ‘A[i]’ to ‘len(S)’ - ‘A[i]’ - 1 (0 based).
Your task is to find the string after performing all the operations.
2. Remove Consecutive Duplicates
Easy
0/40
Asked in companies
For a given string(str), remove all the consecutive duplicate characters.
Example:
Input String: "aaaa"
Expected Output: "a"
Input String: "aabbbcc"
Expected Output: "abc"
Problem approach
You are given a string ‘str’ of size ‘N’. Your task is to remove consecutive duplicates from this string recursively.
For example:
If the input string is ‘str’ = ”aazbbby”, then your output will be “azby”.
Note that we are just removing adjacent duplicates.
