Print uncommon elements from two sorted arrays
Given two sorted arrays, we need to find and print all uncommon elements (elements that appear in one array but not in both). This problem uses a two-pointer technique to efficiently traverse both arrays simultaneously. Given : array1[] = {1, 4, 6, 9, 12} array2[] = {2, 4, 7, 8, 9, 10} Output : 1 2 6 7 8 10 12 Syntax void printUncommonElements(int arr1[], int n1, int arr2[], int n2); Algorithm Initialize two pointers i and j to traverse both arrays ...
Read MorePrint missing elements that lie in range 0 – 99
In C programming, finding missing elements within a specific range is a common problem. Given an array of integers, we need to identify which numbers from 0 to 99 are missing and display them either as individual numbers or as ranges. Syntax bool flag[MAX] = { false }; for (i = 0; i < n; i++) { if (array[i] >= 0 && array[i] < 100) { flag[array[i]] = true; } } Algorithm Create a boolean array flag[100] ...
Read MorePrint the given 3 string after modifying and concatenating
This program demonstrates how to modify multiple strings by replacing all characters with user−specified replacement characters, then concatenate the modified strings together. Syntax strlen(string) // Get string length strcat(dest, source) // Concatenate strings scanf("%s", string) // Read string input Algorithm START Step 1 → Declare three character arrays str1, str2, str3 and replacement characters ch1, ch2, ch3 Step 2 → Input the three strings and three replacement characters Step 3 → Replace all characters in str1 with ...
Read MorePrint number of words, vowels and frequency of each character
In C programming, string analysis is a common task where we need to count words, vowels, and find the frequency of specific characters. This program demonstrates how to analyze a string by counting these different elements in a single pass. Syntax // String traversal for character analysis for(i = 0; str[i] != '\0'; i++) { // Character comparison and counting logic } Algorithm START Step 1: Declare string array, character variable, and counters (freq=0, vowels=0, words=0) Step 2: Input string and target character Step 3: Loop through each character ...
Read MorePrint n numbers such that their sum is a perfect square
Given n numbers, we need to find n numbers whose sum is a perfect square. The solution uses the first n odd numbers, as the sum of first n odd numbers is always n². Input : 5 Output : 1 3 5 7 9 1+3+5+7+9=25 i.e (5)² Syntax for(i = 1; i
Read MoreCount odd and even digits in a number in PL/SQL
We are given a positive integer of digits and the task is to calculate the count of odd and even digits in a number using PL/SQL. PL/SQL is a combination of SQL along with the procedural features of programming languages. It was developed by Oracle Corporation in the early 90's to enhance the capabilities of SQL. PL/SQL is one of three key programming languages embedded in the Oracle Database, along with SQL itself and Java. Input int number = 23146579 Output count of odd digits in a number are : 5 count of even digits in a number are : ...
Read MoreFind elements of an array which are divisible by N using STL in C++
Given with an array and the task is to find the number which are divisible by N using standard template library in C++.To solve this problem we are using the function count_if() present in C++ standard template library.What is a count_if() function?Syntaxcount_if(LowerBound, UpperBound, function)Description − This function returns the number of elements in an array that satisfies the given condition. It takes three parameters.Lower Bound − It points to the first element of an array or any other sequence.Upper Bound − It points to the last element of an array or any other sequence.Function − It returns the Boolean value ...
Read MoreCount number of ways to reach destination in a Maze in C++
Given a Maze represented as a row X col matrix in which the obstacle is represented as -1 and a clear cell has value other than -1. The goal is to start from the first cell arr[0][0] and reach the last cell arr[row][col] such that only two moves are allowed:Right move arr[i][j] to arr[i][j+1] and Down move arr[i][j] to arr[i+1][j].Let us understand with examples.Input - arr[row][col] = {{0, 0, 0}, {-1, -1, 0}, {0, 0, 0}}Output - Count of number of ways to reach destination in a Maze are: 1Explanation 0 1 2 0 0 ...
Read MoreCount numbers in range such that digits in it and it's product with q are unequal in C++
Given two numbers start and end as range variables and an integer q as input. The goal is to find the numbers within a range such that the number and its product with q have no common digits.If the number is 5 and q is 3 then the product will be 15. Both 5 and 15 have a common digit 5.If the number is 2 and q is 5 then the product will be 10. Both 2 and 10 have no common digit.Let us understand with examples.For ExampleInput - start = 5, end = 10, q = 2Output - Count ...
Read MoreCount Numbers in Range with difference between Sum of digits at even and odd positions as Prime in C++
Given two numbers start and end as range variables. The goal is to find the count of numbers that lie in this range [start, end] and have a difference of sum of digits at even and sum of digits at odd positions as Prime.That is (sum of digits at even position)-(sum of digits at odd position) = a Prime numberLet us understand with examples.For ExampleInput - start = 230, end = 270Output - Count of Numbers in Range with difference between Sum of digits at even and odd positions as Prime are: 6Explanation - The number(s) between 230 to 270 ...
