The Pleasant Interactive Shell which is called and abbreviated as FISH is a shell for UNIX and UNIX-like operating systems. It is a unique and innovative command line environment with a number of priceless improvements. Fish is designed to work with any other shell like bash or ZSH. Unlike different shells which disables more than a few elements with the aid of default to save process resource, FISH maintains all of them enabled by means of default in an effort to make most out of it.FeaturesIt is a User-friendly and interactive shellIt has so many powerful featuresInbuilt Web-based configurationIt supported ...

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, 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. Various Techniques to Find Unique Occurrences Following are the various techniques to find the unique occurrence of the elements in a list − ... Read More

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 ...

Suppose, we have a date in the format “YYYY-MM-DD”. We have to return the day number of the year. So if the date is “2019-02-10”, then this is 41st day of the year.To solve this, we will follow these steps −Suppose D is an array of day count like [0, 31, 28, 31, 30, 31, 30, 31, 31, 30, 31, 30, 31]Convert the date into list of year, month and dayif the year is leap year then set date D[2] = 29Add up the day count up to the month mm – 1. and day count after that.ExampleLet us see ...

Suppose we have a list of dominos. Each domino has two numbers. Two dominos D[i] = [a, b] and D[j] = [c, d] will be same if a = c and b = d, or a = d and b = c. So one domino can be reversed. We have to return number of pairs (i, j) for which 0

Suppose we have two arrays arr1 and arr2, the elements of arr2 are unique, and all elements in arr2 are also present in arr1. We have to sort the elements of arr1 in such a way that the relative ordering of items in arr1 are the same as in arr2. If there are some elements that are not present in arr2, they should be placed at the end of arr1 in ascending order. So if the arr1 is like [2, 3, 1, 3, 2, 4, 6, 7, 9, 2, 19], and arr2 is like [2, 1, 4, 3, 9, 6], ... Read More
