Suppose we have an array with n numbers, we have to return the number of consecutive zero’s at the end after multiplying all the n numbers.So, if the input is like [200, 20, 5, 30, 40, 14], then the output will be 6 as 200 * 20 * 5 * 30 * 40 * 14 = 336000000, there are six 0s at the end.To solve this, we will follow these steps −Define a function count_fact_two() . This will take ncount := 0while n mod 2 is 0, docount := count + 1n := n / 2 (only the quotient as ... Read More

Suppose we have one equation in this form: a + b = c, now any one of the terms of a, b or c is missing. We have to find the missing one.So, if the input is like ? + 4 = 9, then the output will be 5To solve this, we will follow these steps −delete all blank spaces from the string and change (+ and = to comma ', ')elements := a list of elements by splitting the string separated by commaidx := 0for i in range 0 to size of elements, doif elements[i] is not numeric, thenidx ...

Suppose there are n number of cashiers exchanging the money, at the moment, the i-th cashier had ki number of people in front of him/her. Now, the j-th person in the line to i-th cashier had m[i, j] notes. We have to find how early can one exchange his/her notes. We have to keep in mind that the cashier spent 5 seconds to scan a single note.After completing scanning of every note for the customer, he/she took 15 seconds to exchange the notes.So, if the input is like Input : n = 6, k = [12, 12, 12, 12, 12, ...

A python tuple is ordered and unchangeable. But it can also be made up of lists as its elements. Given a tuple made up of lists, let’s find out how many lists are present in the tuple.with len()In this approach we will apply the len function. The len() function will give the count of lists which are the elements of the tuple.Example Live DemotupA = (['a', 'b', 'x'], [21, 19]) tupB = (['n', 'm'], ['z', 'y', 'x'], [3, 7, 89]) print("The number of lists in tupA :" , len(tupA)) print("The number of lists in tupB :" , len(tupB))OutputRunning the above ...

Given a list with sorted numbers, we want to find out which numbers are missing from the given range of numbers.With rangewe can design a for loop to check for the range of numbers and use an if condition with the not in operator to check for the missing elements.Example Live DemolistA = [1, 5, 6, 7, 11, 14] # Original list print("Given list : ", listA) # using range res = [x for x in range(listA[0], listA[-1]+1)                               if x not in listA] # ...

If we have a list containing numbers, we can check if the numbers are contiguous or not and also find which numbers are missing from a range of numbers considering the highest number as the final value.With range and maxWe can design a for loop to check for absence of values in a range using the not in operator. Then capture all these values by adding them to a new list which becomes the result set.Example Live DemolistA = [1, 5, 6, 7, 11, 14] # Original list print("Given list : ", listA) # using range and max res ...

Sometimes we may need to compare elements in two python lists in terms of both their value and position or index. In this article we will see how to find out the elements in two lists at the same position which do not match in their value.Using for loopwe can design for loop to compare the values at similar indexes. Id the values do not match then we add the index to a result list. The for loop first fetches the value in the first index and then uses an if condition to compare it with values from the second ...

A python list can contain both strings and numbers. We call it a heterogeneous list. In this article we will take such a list and find the minimum and maximum number present in the list.Finding MinimumIn this approach we will take the isinstance function to find only the integers present in the list and then apply the min function to get the minimum value out of it.Example Live DemolistA = [12, 'Sun', 39, 5, 'Wed', 'Thus'] # Given list print("The Given list : ", listA) res = min(i for i in listA if isinstance(i, int)) # Result print("The ...

Numpy is a very powerful python library for numerical data processing. It mostly takes in the data in form of arrays and applies various functions including statistical functions to get the result out of the array. In this article we will see how to get the mean value of a given array.with meanThe mean function can take in an array and give the mathematical mean value of all the elements in it. So we design a for loop to keep track of the length of the input and go through each array calculating its mean.Example Live Demoimport numpy as np ... Read More
