Suppose we have two digits a and b. We shall have to convert each digit into words and print them one by one. Printing digits into words means for a digit 5, it should print "Five".So, if the input is like a = 2, b = 6, then the output ... Read More

Suppose we have a digit d, we shall have to convert it into words. So if d = 9, our output should be "Nine". If we provide some d which is beyond the range of 0 and 9, it will return appropriate output.So, if the input is like d = ... Read More

Suppose we have a number n, we have to transform it into 0 using the following operations any number of times −Select the rightmost bit in the binary representation of n.Change the ith bit in the binary representation of n when the (i-1)th bit is set to 1 and the ... Read More

Suppose, there are n number of hostel rooms numbered from 0 to n-1. The students in the hostel rooms want to transfer to another room, and they place several requests to do that. No hostel seat remains vacant, a transfer request is only taken care of if another student takes ... Read More

Suppose we have two numbers a and b, a is integer and b is a float. We shall have to take them from standard input and display the sum.So, if the input is like a = 10 b = 56.23, then the output will be Sum: 66.23To solve this, we ... Read More

Suppose, we are given a grid where the cells contain various symbols such as 'X', 'O', '*' and '#' and the symbols have various meanings.'#' is the goal cell that we want to reach.'O' is a free cell via which we can travel to the goal cell.'*' is our position ... Read More

Suppose we have an m x n binary matrix, we can rearrange the columns of the matrix in any order. We have to find the area of the largest submatrix within matrix where every element of the submatrix is 1 after performing some reordering task.So, if the input is like101111001then ... Read More

Suppose we have a list of numbers nums. We also have a list of queries where queries[i] contains three elements [k, p, r], for each query we shall have to find kpr_sum. The formula for kpr_sum is like below.$$\mathrm{{𝑘𝑝𝑟}\_{𝑠𝑢𝑚} =\sum_{\substack{𝑖=𝑃}}^{𝑅−1}\sum_{\substack{𝑗=𝑖+1}}^{𝑅}(𝐾 ⊕(𝐴[𝑖]⊕𝐴[𝑗]))}$$If the sum is too large, then return sum modulo ... Read More

Suppose we have three numbers i, j and k and another number n. We shall have to find the list of all triplets (i, j, k) for which i+j+k not same as n. We shall have to solve this problem using list comprehension strategy.So, if the input is like i ... Read More

Suppose we have an array nums with unique positive values, we have to find the number of tuples (a, b, c, d) such that a*b = c*d where a, b, c, and d are elements of nums, and all elements a, b, c and d are distinct.So, if the input ... Read More
