Read MoreSum of numbers formed by consecutive digits present in a given string
Problem Statement We have given a string str containing the numeric and alphabetical characters. We need to find the sum of all numbers represented by a continuous sequence of digits available in the given string. Sample Examples Input str = “12were43” Output 55 Explanation The sum of 12 and 43 is equal to 55. Input str = “1a2c3d” Output 6 Explanation The sum of 1, 2, and 3 is 6. Input str = “werderfrewsf” Output 0 Explanation It gives 0 in the output as the string contains no digit. Our logic to solve the ...
Read MoreModify a Sentence By Reversing Order Of Occurrences Of All Palindrome Words
Problem Statement We have given a string str containing a total of N words. We need to find all palindrome words in the given string and create a new string by reversing the order of all palindrome words. Sample Examples Input str = ‘nayan was gone to navjivan eye hospital’ Output ‘eye was gone to navjivan nayan hospital’ Explanation The string contains three palindrome words: nayan, navjivan, and eye. We have reversed the order of all three words and kept all other words the same. Input ‘Hello, users! How are you?’ Output ‘Hello, users! How are you?’ ...
Read MoreDifference between GO and Erlang
Go and Erlang are two popular programming languages that are frequently utilized for building large-scale, conveyed, and fault-tolerant frameworks. Whereas both languages have their claims and various kinds of highlights and qualities, both share a common objective of giving designers effective devices for building versatile and adaptable frameworks. In this article, we'll compare Go and Erlang in terms of their concurrency models, fault-tolerance highlights, syntax, performance, and community support. By understanding the qualities and shortcomings of these two languages, developers can make educated choices approximately as to which language to utilize for their next project. Go Go is outlined for ...
Read MoreMinimum Removals Required To Place All 0s Before 1s In a Binary String
Problem Statement We have given binary string str, and we require to remove minimum characters from the string such that we can place all zeros before 1. Sample Examples Input str = ‘00110100111’ Output 3 Explanation Here, we can achieve output 3 in two ways. We can either remove arr[2], arr[3], and arr[5] or arr[4], arr[6], and arr[7] from the string. Input str = ‘001101011’ Output 2 Explanation We can remove arr[4] and arr[6] to place all zeros before 1. Input str = ‘000111’ Output 0 Explanation In the given str, all ...
Read MoreMinimum Number That Can Be Obtained By Applying \'+\' And \'*\' Operations On Array Elements
Problem Statement We have given an array of length ‘N’ containing some positive integers. Also, we have given the string of length ‘N-1’ containing only ‘*’ and ‘+’ characters, where ‘*’ is a multiplication operator, and ‘+’ is an addition operator. We require to perform the arithmetic operation with array elements in such a way that we can get a minimum positive integer value. Sample Examples Input array = [1, 2, 3], str = “*+” Output 5 Explanation It is the resultant value of ((1*2) + 3). Input array = [3, 3, 3, 3], str = ‘*++’ ...
Read MoreMake a String Non-Palindromic By Inserting a Given Character
Problem Statement We have given a string str and character c in the input. We need to insert the given character c in the string at the index so that we can convert the string to non-palindromic. If we can’t convert the string to non-palindrome, print ‘-1’. Sample Examples Input str = ‘nayan’, c = ‘n’ Output ‘nnayan’ Explanation There can be multiple output strings as we can insert ‘n’ at any index in the given string. So, the output string can be ‘nnayan’, ‘nanyan’, ‘naynan’, ‘nayann’, etc. Input str = ‘sss’, c = ‘s’ Output ‘-1’ ...
Read MoreLexicographically Largest String With Sum Of Characters Equal To N
Problem Statement We have given a positive integer num. We need to find the lexicographically largest string of lowercase alphabetical characters such that the sum of all characters of the string is equal to num. Here, ‘a’ = 1, ‘b’ = 2, ‘c’ = 3, ‘d’ = 4, …., ‘z’ = 26. We need to use the ‘z’ characters at the string's start to create the largest lexicographical string. At last, we need to use the last character according to the num % 26 value. Sample Examples Input num = 30 Output ‘zd’ Explanation The ‘zd’ is the ...
Read MoreDistinct Numbers Obtained By Generating All Permutations Of a Binary String
Problem Statement We have given binary string str of length N. We need to find all permutations of the string, convert them to the decimal value, and return all unique decimal values. Sample Examples Input str = ‘1’ Output [1] Explanation All permutations of the ‘1’ is only ‘1’. So, the decimal value related to ‘1’ equals 1. Input str = ‘10’ Output [1, 2] Explanation The permutations of ‘10’ are only ‘01’ and ‘10’, equivalent to 1 and 2, respectively. Input ‘101’ Output [3, 5, 6] Explanation All possible permutations of ‘101’ are ...
Read MoreCount Intervals That Intersects With a Given Meeting Time
Problem Statement We have given a two-dimensional array containing the pairs of starting and ending times for time intervals in the 12-hour format. Also, we have given string str in the 12-hour time format. We need to find a total number of intervals which included the time represented by str. Sample Examples Input arr[][2] = {{“12:02:AM”, “10:55:PM”}, {“12:51:AM”, “11:40:AM”}, {“01:30:AM”, “12:00:PM”}, {“11:57:PM”, “11:59:PM”}}, str = “2:30:AM” Output 3 Explanation The time “2:30:AM” intersects the first three intervals. Input arr[][2] = {{“01:02:PM”, “10:55:PM”}, {“01:30:AM”, “11:00:AM”}}, str = “11:30:PM” Output 0 Explanation The ...
