Suppose we have two sorted lists A and B. We have to merge them and form only one sorted list C. The size of lists may different.For an example, suppose A = [1,2,4,7] and B = [1,3,4,5,6,8], then merged list C will be [1,1,2,3,4,4,5,6,7,8]We will solve this using recursion. So the function will work like below −x:= a new listi:= 0, j:= 0while i < size of (lst0) and j < size of (lst1), doif lst0[i] > lst1[j], theninsert lst1[j] at the end of xj:= j+1otherwise when lst0[i]

Suppose we have a list of numbers called nums, we have to divide it into two parts of same size where the absolute difference between each list's median is as small as possible and we have to find this difference. We have to keep in mind that here length of nums / 2 will be odd.So, if the input is like [2, 10, 8, 5, 4, 7], then the output will be 2, as we can make two lists like [2, 5, 10] and [4, 7, 8], then the medians are 5 and 7, their difference is 2.To solve this, ...

Suppose we have a lowercase string s, we have to find how many "pizza" strings we can make using the characters present in s. We can use the characters in s in any order, but each character can be used once.So, if the input is like "ihzapezlzzilaop", then the output will be 2.To solve this, we will follow these steps −p_freq := Frequency of 'p' in si_freq := Frequency of 'i' in sz_freq := Frequency of 'z' in sa_freq := Frequency of 'a' in sreturn minimum of (p_freq, i_freq, z_freq/2 and a_freq)Let us see the following implementation to get better ...

Suppose we have a list of numbers called nums, we have to find the maximum length of a contiguous strictly increasing sublist when we can remove one or zero elements from the list.So, if the input is like nums = [30, 11, 12, 13, 14, 15, 18, 17, 32], then the output will be 7, as when we remove 18 in the list we can get [11, 12, 13, 14, 15, 17, 32] which is the longest, contiguous, strictly increasing sublist, and its length is 7.To solve this, we will follow these steps−n := size of numspre := a list ...

Suppose we have two strings s and t of length n. We can take one character from s and another from t and swap them. We can make unlimited number of swaps; we have to check whether it's possible to make the two strings equal or not.So, if the input is like s = "xy", t = "yx", then the output will be TrueTo solve this, we will follow these steps −st:= sort the string after concatenating s and tfor i in range 0 to size of st - 1, increase by 2, doif st[i] is not same as st[i+1], ...

Suppose we have a string s, we have to find the length of the longest substring with same characters.So, if the input is like "abbbaccabbbba", then the output will be 4, as there are four consecutive b's.To solve this, we will follow these steps −if size of s is 0, thenreturn 0s := s concatenate blank spacect:= 1, tem:= 1for i in range 0 to size of s -2, doif s[i] is same as s[i+1], thentem := tem + 1otherwise, ct:= maximum of tem and cttem:= 1return ctLet us see the following implementation to get better understanding −Example Live Democlass Solution: ...

Suppose we have a list of numbers called nums, we have to replace every nums[i] with the smallest element left of i. We have to replace nums[0] with 0.So, if the input is like [15, 7, 9, 16, 12, 25], then the output will be [0, 15, 7, 7, 7, 7]To solve this, we will follow these steps −if nums is empty, thenreturn a new listj:= nums[0]nums[0]:= 0for i in range 1 to size of nums - 1, dok:= nums[i]nums[i]:= jj:= minimum of j, kreturn numsLet us see the following implementation to get better understanding −Example Live Democlass Solution:    def ...

Suppose we have given a list of numbers called nums, we want to make the values equal. Now let an operation where we pick one element from the list and increment every other value. We have to find the minimum number of operations required to make element values equal.So, if the input is like [2, 4, 5], then the output will be 5.To solve this, we will follow these steps −min_val := minimum of numss := 0for each num in nums, dos := s + (num - min_val)return sLet us see the following implementation to get better understanding −Example Live Democlass ...
