Program to shuffle string with given indices in Python
Suppose we have a string s and a list of indices ind, they are of same length. The string s will be shuffled such that the character at the position i, moves to indices[i] in the final string. We have to find the final string.So, if the input is like s = "ktoalak" ind = [0, 5, 1, 6, 2, 4, 3], then the output will be "kolkata"To solve this, we will follow these steps −fin_str := a list whose size is same as s and fill with 0for each index i and character v in s, dofin_str[ind[i]] := vjoin ...
Read MoreProgram to count odd numbers in an interval range using Python
Suppose we have two non-negative numbers left and right. We have to find the number of odd numbers between left and right (inclusive).So, if the input is like left = 3, right = 15, then the output will be 7 because there are 7 odd numbers in range, these are [3, 5, 7, 9, 11, 13, 15], there are 7 elements.To solve this, we will follow these steps −if left is odd or right is odd, thenreturn 1 + quotient of (right-left) / 2otherwise, return quotient of (right-left) / 2Example (Python)Let us see the following implementation to get better understanding ...
Read MoreProgram to find maximum how many water bottles we can drink in Python
Suppose there are n number of full water bottles, we can exchange m empty water bottles for only one full water bottle. Now drinking a full water bottle makes it an empty bottle. We have to find the maximum number of water bottles we can drink.So, if the input is like n = 9, m = 3, then the output will be 13 because initially we have 9 bottles, so after drinking all bottles, we can get 9/3 = 3 full bottles, after drinking them all we have three empty bottles and using them we can buy one and drink ...
Read MoreProgram to reformat date in YYYY-MM-DD format using Python
Suppose we have a date string in the format "Day Month Year" format where day's are like [1st, 2nd, ..., 30th, 31st], months are in [Jan, Feb, ... Nov, Dec] format and year is a four-digit numeric value in range 1900 to 2100, we have to convert this date into "YYYY-MM-DD" format.So, if the input is like date = "23rd Jan 2021", then the output will be 2021-01-23To solve this, we will follow these steps −Months:= ["Jan", "Feb", "Mar", "Apr", "May", "Jun", "Jul", "Aug", "Sep", "Oct", "Nov", "Dec"]string:= split the date and form a list like [day, month, year] formatyear ...
Read MoreProgram to check we can make arithmetic progression from sequence in Python
Suppose we have a list of numbers called nums. We have to check whether the elements present in nums are forming AP series or not. As we know in AP (Arithmetic Progression) series the common difference between any two consecutive elements is the same.So, if the input is like nums = [9, 1, 17, 5, 13], then the output will be True because if we sort them, it will be [1, 5, 9, 13, 17] and here common difference is 4 for each pair of elements.To solve this, we will follow these steps −nums := sort the list numsif number ...
Read MoreProgram to find average salary excluding the minimum and maximum salary in Python
Suppoe we have an array with distinct elements called salary where salary[i] is the salary of ith employee. We have to find the average salary of employees excluding the minimum and maximum salary.So, if the input is like salary = [8000, 6000, 2000, 8500, 2500, 4000], then the output will be 5125.0, as the minimum and maximum salary values are 2000 and 8500, so excluding them the average salary values are [8000, 6000, 2500, 4000] so the average is (8000 + 6000 + 2500 + 4000)/4 = 5125.To solve this, we will follow these steps −delete minimum of salary from ...
Read MoreProgram to perform XOR operation in an array using Python
Suppose we have an integer n and another integer start. We have to create an array called nums where nums[i] = start + 2*i (i start from 0) and n is the size of nums. Then find the bitwise XOR of all elements of nums.So, if the input is like n = 6, start = 2, then the output will be 14 because the array will be like [2+2*0, 2+2*1, ... 2+2*5] = [2, 4, 6, 8, 10, 12], then XOR of each element present in the array is 14.To solve this, we will follow these steps −count := startwhile ...
Read MoreProgram to find running sum of 1d array in Python
Suppose we have an array nums. The running sum of an array as rs[i] is sum of all elements from nums[0] to nums[i]. Finally return the entire running sum of nums.So, if the input is like nums = [8, 3, 6, 2, 1, 4, 5], then the output will be [8, 11, 17, 19, 20, 24, 29], becausers[0] = nums[0] rs[1] = sum of nums[0..1] = 8 + 3 = 11 rs[2] = sum of nums[0..2] = 8 + 3 + 6 = 17 and so onTo solve this, we will follow these steps −n:= size of numsrs:= [nums[0]]for i ...
Read MoreProgram to find Final Prices With a Special Discount in a Shop in Python
Suppose we have an array called prices where prices[i] represents price of the ith item in a shop. There is a special offer going on, if we buy the ith item, then we will get a discount equivalent to prices[j] where j is the minimum index such that j > i and price of jth item is less or same as price of ith item (i.e. prices[j] = prices[j], thenprices[i] := prices[i] - prices[j]come out from the loopotherwise, j := j + 1return pricesExample (Python)Let us see the following implementation to get better understanding − Live Demodef solve(prices): for i ...
Read MoreProgram to delete n nodes after m nodes from a linked list in Python
Suppose we are given a linked list that has the start node as "head", and two integer numbers m and n. We have to traverse the list and delete some nodes such as the first m nodes are kept in the list and the next n nodes after the first m nodes are deleted. We perform this until we encounter the end of the linked list. We start from the head node, and the modified linked list is to be returned.The linked list structure is given to us as −Node value : next : So, if the ...
