Suppose we have two lists of numbers called A, and B. We have to take some sublist in A and reverse it. Then check whether it is possible to turn A into B or not. We can take sublist and reverse it any number of times.So, if the input is ... Read More

Suppose we have a string, we have to check whether it's a repeating string or not.So, if the input is like string = "helloworldhelloworld", then the output will be TrueTo solve this, we will follow these steps −n := size of sDefine a function findFactors() . This will take nf ... Read More

Suppose we have a string s and a number k, we have to find the number of k-length substrings of s, that occur more than once in s.So, if the input is like s = "xxxyyy", k = 2, then the output will be 2To solve this, we will follow ... Read More

Suppose we have a positive number n, we will add all of its digits to get a new number. Now repeat this operation until it is less than 10.So, if the input is like 9625, then the output will be 4.To solve this, we will follow these steps −Define a ... Read More

Suppose we have two strings s and t, we have to check whether we can get t by removing 1 letter from s.So, if the input is like s = "world", t = "wrld", then the output will be True.To solve this, we will follow these steps −i:= 0n:= size ... Read More

Suppose we have a list of numbers A, we have to find all duplicate numbers and remove their last occurrences.So, if the input is like [10, 30, 40, 10, 30, 50], then the output will be [10, 30, 40, 50]To solve this, we will follow these steps −seen:= a new ... Read More

Suppose we have a list of numbers called A and another number k, we have to make a new set of possible elements {A[k], A[A[k]], A[A[A[k]]], ... } stopping before it's out of index. We have to find the size of this set, otherwise -1 when there is a cycle.So, ... Read More

Suppose we have a string s, we have to find the index of the first recurring character in it. If we cannot find no recurring characters, then return -1.So, if the input is like "abcade", then the output will be 3, as 'a' is again present at index 3.To solve ... Read More

Suppose we have a rectangle that is represented as a list with four elements [x1, y1, x2, y2], where (x1, y1) is the coordinates of its bottom-left corner, and (x2, y2) is the coordinates of its top-right corner. Two rectangles overlap when the area of their intersection is positive. So, ... Read More

Suppose we have a list of numbers called nums, we have to check whether there exist three numbers a, b, and c such that a^2 + b^2 = c^2.So, if the input is like [10, 2, 8, 5, 6], then the output will be True, as 8^2 + 6^2 = ... Read More
