Suppose we have a string s and another character c, c must be present in s, we have to find a list whose length is same as length of s where for each index i its value is set the closest distance of s[i] to c.So, if the input is ... Read More

Suppose there are two spheres whose radius values are r1 and r2. They are at (x1, y1, z1) and (x2, y2, z2) coordinates. And their acceleration values are given like (ax1, ay1, az1) and (ax2, ay2, az2). We have to check whether these two spheres will ever meet on 3D ... Read More

Suppose we have a number n. We have to check whether this is power of 2 or not.So, if the input is like n = 2048, then the output will be True as 2048 is 2^11.To solve this, we will follow these steps −if n is same as 0, thenreturn ... Read More

Suppose we have a number n, we have to check whether n is a perfect square number or not. A perfect square number k can be represented as k = a * a for some integer a. We have to solve this without using built-in square root function.So, if the ... Read More

Suppose we have an alphanumeric string s with digits from "0" to "9" and lowercase English letters. We have to find the sum of the numbers that are present in s. If digits are consecutive then consider them into a single number.So, if the input is like s = "hello25world63power86", ... Read More

Suppose we have a list called nums, we have to check whether we can rearrange the order of nums in such a way that the difference between every pair of consecutive two numbers is same.So, if the input is like nums = [8, 2, 6, 4], then the output will ... Read More

Program to find the maximum sum of the subarray modulo by m in PythonSuppose we have an array nums with n elements. We have another integer m. We have to find the maximum value of sum of any of its subarrays modulo m.So, if the input is like nums = ... Read More

Suppose we have a string s whose length is n. We also have a list of queries Q, where Q[i] contains a pair (l, r). For each query we have to count number of different substrings of s in the inclusive range between l and r.So, if the input is ... Read More

Suppose we have list of numbers called nums and another two variables k and t. Let us consider an operation where we choose an element say e in range [-k, k] and insert it to nums at the end. We have to find the minimum number of operations needed so ... Read More

Suppose we have an array called nums, containing decimal digits of a number. For example, [2, 5, 6] is for 256. We have to add 1 with this number and return the list in same format as before.So, if the input is like nums = [2, 6, 9], then the ... Read More
