Read MoreFind Numbers with Even Number of Digits in Python
Given a list of numbers, we need to count how many numbers have an even number of digits. For example, if the array is [12, 345, 2, 6, 7896], the output will be 2, since 12 (2 digits) and 7896 (4 digits) have even digit counts. Approach To solve this problem, we will follow these steps − Convert each integer to a string to easily count digits Check if the length of the string is even using modulo operation Increment counter for numbers with ...
Read MoreUnique Number of Occurrences in Python
Suppose we have an array, and we need to check whether each element has a unique number of occurrences. If no such element exists, we return false; otherwise, we return true. For example, given the array [1, 1, 2, 2, 2, 3, 4, 4, 4, 4], the function will return true because no two elements have the same number of occurrences: 1 occurs twice, 2 occurs three times, 3 occurs once, and 4 occurs four times. Using Dictionary to Track Occurrences A dictionary is ideal for counting occurrences since it stores key-value pairs where keys are unique elements ...
Read MorePrime Arrangements in Python
We need to find the number of permutations of numbers 1 to n where prime numbers are placed at prime indices (1-indexed). Since the result can be large, we return it modulo 10^9 + 7. For example, if n = 5, the output is 12. One valid permutation is [1, 2, 5, 4, 3], while [5, 2, 3, 4, 1] is invalid because 5 (prime) is at index 1 (not prime). Algorithm The key insight is that we need to arrange prime numbers in prime positions and non-prime numbers in non-prime positions separately ? Count ...
Read MoreDay of the Year in Python
Sometimes we need to find which day of the year a specific date represents. For example, February 10th, 2019 is the 41st day of the year. Python provides several ways to calculate this using date manipulation. Algorithm Approach To calculate the day of the year manually, we follow these steps − Create an array of days in each month: [0, 31, 28, 31, 30, 31, 30, 31, 31, 30, 31, 30, 31] Parse the date string to extract year, month, and day Check if the year is a leap year and adjust February days to 29 ...
