Maximum number of people that can be killed with strength P in C++
Given the task is to find the maximum number of people that can be killed with strength P. Consider a row with infinite people and each of them have an index number starting from 1.The strength of the sth person is represented by s2. After killing a person with s strength your strength also decreases by s.Let’s now understand what we have to do using an example −InputP = 20Output3ExplanationStrength of 1st person = 1 * 1 = 1 < 20, therefore 1st person can be killed. Remaining strength = P – 1 = 20 – 1 = 19 Strength ...
Read MoreMaximum number of removals of given subsequence from a string in C++
Given the task is to find the maximum number of removals of given subsequence from a string. A string s is given and we have to find the maximum number of subsequence ‘abc’ that can be removed from the string.Let’s now understand what we have to do using an example:Inputs = ‘dnabcxy’Output1Explanation − Only one subsequence of ‘abc’ can be found in the given string (‘dnabcxy’), therefore the output is 1.Inputs = ‘zcabcxabc’Output2 (‘zcabcxabc’)Approach used in the below program as followsIn Max() function initialize variables i, a, ab, abc with value = 0 and of type int.Loop from i=0 till ...
Read MoreMaximum number of squares that can fit in a right angle isosceles triangle in C++
Given the task is to find the maximum number of squares having side ‘a’ that can fit inside a give right angle isosceles triangle with base of ‘s’(An isosceles triangle has at least 2 equal sides).Let’s now understand what we have to do using an example:Inputs=5, a=1Output10Explanation − The number of squares in the base can be calculated by dividing s by a and subtracting 1. So the number of squares in base = 5/1 – 1 = 4.Similarly when the bottom 4 squares are placed then we get a new isosceles triangle with base (s-a) and then we repeat ...
Read MoreMaximum count of substrings of length K consisting of same characters in C++
Given the task is to find the maximum count of substrings of length K consisting of same characters. Given a string s and another integer K, we have to count the occurrence of sub-strings of size K that have same characters.Out of the sub-strings that are found, we have to choose the sub-string occurring the maximum number of time.Let’s now understand what we have to do using an example −Inputs = ”tuuxyyuuc”, K = 2Output2ExplanationHere the sub-strings of length 2 and having same characters are: “uu” and “yy” but as it is seen that “yy” occurs only 1 time and ...
Read MoreMaximum decimal value path in a binary matrix in C++
Given the task is to find the maximum integer value that can be obtained while travelling in a path from the top left element to the bottom right element of a given square binary array, that is, starting from index [0][0] to index [n - 1][n - 1].While covering the path we can only move to right ([i][j + 1]) or to the bottom ([i + 1][j])The integer value will be calculate using the bits of the traversed path.Let’s now understand what we have to do using an example −Inputm = { {1, 1, 1, 1}, {0, 0, ...
Read MoreMaximum difference of zeros and ones in binary string in C++
Given the task is to find a sub-string from a given binary string and then the maximum difference between the number of zeroes and the ones.Let’s now understand what we have to do using an example −Inputstr = “100100110”Output2ExplanationIn the sub-array from the position 1 to 5 (“00100”), the difference between the zeros and ones = 4 – 1 = 3 which is the maximum that can be found.Inputstr = “00000”Output5Approach used in the below program as followsIn main() function create a string str to store the binary string. Also initialize a variable int size to store the size of ...
Read MoreMaximum distinct lowercase alphabets between two uppercase in C++
Given the task is to find the maximum number of distinct lower case alphabets that are present between two upper case alphabets in the given string.Let’s now understand what we have to do using an example −Inputstr = “JKyubDoorG”Output3Explanation“yub” is present between the two upper case alphabets K and D which makes the count 3.“oor” is also present between the two upper case alphabets D and G which makes the count 2 as ‘o’ is a repeating alphabet and we are looking for distinct alphabets.Therefore, the output is 3.Inputstr = “ABcefsTaRpaep”Output4Approach used in the below program as followsIn function Max() ...
Read MoreMaximum elements that can be made equal with k updates in C++
Given the task is to find the maximum number of elements that can be made equal in a given array after incrementing its elements by at-most k times.Let’s now understand what we have to do using an example −Inputa[] = {1, 3, 8}, k = 4Output2ExplanationHere we can obtain two fours by incrementing 1 three times and incrementing 3 four times, that makes a[] = {4, 4, 8}Inputarr = {2, 5, 9}, k = 2Output0Approach used in the below program as followsIn main() function initialize int a[], size and k to store the array elements, size of array and the ...
Read MoreMaximum elements which can be crossed using given units of a and b in C++
Given a binary array arr[] and two variables a and b with some initial values. To cross an element in the array arr[] there are two ways −If arr[i] == 1, then 1 unit can be used from a, with no change in b. If 1 unit is used from b, then a increases by 1 unit. (Note that the value of a cannot be incremented above its original value.)If arr[i] == 0, then 1 unit can be used from a or b.Let’s now understand what we have to do using an example −Inputarr[] = {0, 0, 0, 1, 1}, ...
Read MoreRotation of a point about another point in C++
Rotation of a point X about origin is by an angle θ in anti-clockwise direction is done by − X by θ about origin anti-clRotateockwise: X*polar( 1.0, θ ).Here, the function polar for complex numbers is defined under header file and is used to find a complex number using phase angle and magnitude. polar(mag, angle) returns a complex number.Rotation of point X about a point YTo rotate a point about another point, we will use translation in which movement of all coordinates occur in a particular direction.Steps to rotate X about Y.Translate X to Y, so Y becomes the new ...
