Objective: Given an array of integers (in particular order or permutation of a set of numbers), write an algorithm to find the lexicographically previous permutation of the given permutation with only one swap. This...
Objective: Given two strings with equal lengths, write an algorithm to calculate the hamming distance between the strings. Hamming Distance: Hamming distance between two strings is the number of positions at which the characters...
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 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: Given an Integer, write a program to convert it to Roman number. This problem can be stated as “Convert Decimal to Roman String” OR “Convert numeral value to Roman numeral”. Roman Number –...
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 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 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:...
