Objective: You are working on a project where QA team has automated set of test cases for the project, but these test cases have to be executed in a specific order since test cases...
Given a string with alphabets and numbers. Write an algorithm to find the maximum number in the string. If any number is greater than equal to Max_Value of integer then return the Max_Value. Example:...
Objective: Given a Prefix expression, write an algorithm to convert it into Postfix expression. Example: Input: Prefix expression: + A B Output: Postfix expression: A B + Input: Prefix expression: *-A/BC-/AKL Output: Postfix expression:...
Objective: Given a Roman number, write a program to convert it to Integer. Roman Number – Letters used in Roman numerals and the corresponding numerical values are given in the table below. Rules: ...
Objective: Given a Postfix expression, write an algorithm to convert it into prefix expression. Example: Input: Postfix expression: A B + Output: Prefix expression- + A B Input: Postfix expression: ABC/-AK/L-* Output: Infix expression:...
Objective: Write a recursive function to implement atoi, which converts string to an integer. Rules for converting string to an integer. If the string is null or empty, Integer will be 0. The first...
Objective: Given an array of strings, write an algorithm to group the anagrams. Example: Input: [rat, art, cat, act, dog, god, tar, pat] Output: [rat, art, tar] [cat, act] [pat] [dog, god] Approach: If...
Problem Statement: There is an application that has several processes running in parallel and each process prints the logs in a single log file. Log message contains the process name, timestamp, message type (WARN,...
Objective: Given an input string, write an algorithm to find the longest contiguous character or in other words, find a maximum consecutive character in the string. Example: Input: “aaabbccccddbbaaa” Output: c, count = 4...
Objective: Given a Postfix expression, write an algorithm to convert it into Infix expression. Example: Input: Postfix expression: A B + Output: Infix expression- (A + B) Input: Postfix expression: ABC/-AK/L-* Output: Infix expression:...
Objective: Implement atoi, which converts string to an integer. Rules for converting string to an integer. If the string is null or empty, Integer will be 0. The first character of string may represent...
Objective: Given a string, write an algorithm to find the longest substring with at most two characters. Example: Input: aabbccddc Output: ccddc, length: 5 Input: aabacbeeeebeaabb Output: beeeebe, length 7 Input: aaaaaa Output: Only...
Objective: Given a number N, find the largest number which is less than equal to N and has monotone increasing digits. Monotone Increasing Digits – If all the pairs (x, y) of adjacent digits...
Objective: Given a Prefix expression, write an algorithm to convert it into Infix expression. Example: Input: Prefix expression: + A B Output: Infix expression- (A + B) Input: Prefix expression: *-A/BC-/AKL Output: Infix expression:...
Objective: Given an Infix expression, write an algorithm to convert it into Prefix expression. Example: Input: Infix expression – A + B Output: Prefix expression- +AB Input: Infix expression – A+B*(C^D-E) Output: Prefix expression-...
