Suppose we have a list of numbers. We have to count the numbers that has even number of digit count. So if the array is like [12, 345, 2, 6, 7896], the output will be 2, as 12 and 7896 has even number of digitsTo solve this, we will follow these steps −Take the list and convert each integer into stringif the length of string is even, then increase count and finally return the count valueExampleLet us see the following implementation to get better understanding − Live Democlass Solution(object): def findNumbers(self, nums): str_num = map(str, nums) ...

Suppose we have an array. We have to check whether each element has unique number of occurrences. If no such element is present then return false, otherwise true. So if the array is like [1, 1, 2, 2, 2, 3, 4, 4, 4, 4], then it will return true as the element 1 is present two times, 2 is present three times, 3 is present once and 4 is present four times.To solve this, we will follow these steps −We will find the frequency of elements of the arrayfor each key-value pair in the frequency mapif value is present in ...

We have to find the number of permutations of 1 to n, so the prime numbers are placed at prime indices. The answers may be large, return the answer modulo 10^9 + 7. So if n = 5, then output will be 12. So there will be 12 permutations. one possible permutation will be [1, 2, 5, 4, 3], one invalid permutation is [5, 2, 3, 4, 1] because 5 is placed at index 1, that is not prime.To solve this, we will follow these steps −Define one method called getNum, as follows −prime := list of all primes from ...
