Convert string to int, requires us to convert a numeric string given to an integer. Here we are assuming, we are provided with a numeric string without white spaces either in the middle of the characters or at any one of the ends. We are also assuming that the string …
Problem Statement You have given an integer array and a number k. The problem statement asks to find the subarray with least average, which is to find out the sub-array of k elements, which has the minimum average. Example arr[] = {12, 34, 20, 30, 24, 45} k = 3 Sub-Array of [0, 2] has a minimum average. Explanation: …
Problem Statement You are given an array of integers. The problem statement asks to find minimum number of merge operations to make an array palindrome, i.e. find out the minimum number of merging operations to be done on the array to make it a palindrome. Merging operation simply means that …
Problem Statement Suppose you have an array of integers and each element of an array indicates each number as maximum jumps that can be taken from that point. Your task is to find out the minimum number of jumps to reach end, i.e. minimum of jumps that can be taken …
Problem Statement Suppose you have an array containing only integer 0 as all of its elements. Consider, you are given an array of length n having all 0s in which we have to convert the 0s to the given required array. We can name the required array as the desiredArr …
