Birthday Cakes
Find the count of tallest candle that can be blown out

You are in charge of the cake for your daughter's birthday and have decided the cake will have one candle for each year of her total age. When she blows out the candles, she'll only be able to blow out the tallest ones. Your task is to find out how many candles she can successfully blow out.

For example, if your daughter is turning 4 years old, and the cake will have 4 candles of height 4, 4, 1, 3, she will be able to blow out 2 candles successfully, since the tallest candles are of height and there are such candles.

Input: An array containing height of candle [4,4,1,3]

Output: Print the number of candles that can be blown out. 2

Explanation: We have one candle of height 1, one candle of height 2, and two candles of height 3. Your daughter only blows out the tallest candles, meaning the candles where height=3. Because there are 2 such candles, we print 2.

Min and max values
Algorithm in php to find minimum and maximum values of an array using single loop

Given five positive integers, find the minimum and maximum values that can be calculated by summing exactly four of the five integers. Then print the respective minimum and maximum values as a single line of two space-separated long integers.

For example, arr=[1,3,5,7,9] . Our minimum sum is 1+3+5+7 and our maximum sum is 3+5+7+9. We would print 16 24

Monkey man algorithm
Monkey man algorithm, who jumps and slip on wall

A monkey man caught inside a jail. He can jumps across the wall. He can jump 'X' meters, but due to slippery walls he falls 'Y' meters after each jump. To escape from jail, he has to cross 'N' number of walls, where height of each wall is given in an array.

Write a program to find total number of jumps, he has to make, to escape

Input Format

Your function will take three arguments, where:

Argument 1: An integer depicting X, which he can jump

Argument 2: An integer depicting Y, which he falls

Argument 3: An array of N integers having the height of each wall.




Output Format

Your program should return total number of jumps required to escape.

Sample Test Case

Test case 1

Sample Input 10 1 1 10

Sample Output 1


Here monkey man can jump 10 meters high, but slides down by 1 meter. He has 1 wall to jump and the height of the wall is 10 meters. Since he jumps 10 meters in the first attempt he cross the wall easily in the first attempt only.

Test case 2

Sample Input 5 1 2 9 10

Sample Output 5


Here, the monkey man can jump 5 meters high, but slides down by 1 meters. He has 2 walls to jump and the walls are 9 and 10 meters hight respectively.

While crossing the first wall, he takes 2 attempts, because during the first attempt he jumps 5 meters but slides down by 1 meters since he didn't cross the wall. In the next attempt he jumps 5 more meters from that position and this time he doesn't slide because he crossed the wall in this attempt because 4+5=9 and 9 meters is the actual height of the wall.

Similarly, while crossing the second wall, he takes 3 attempts because during his second attempt on this wall, he silides down by 1 meters since 4+5=9 and the height of the wall is 10 meters. During his third attempt, he was able to escape.

Tidy number
Tidy Numbers - Display all positive integers in ascending order

Ananya likes to keep things tidy. Her toys are sorted from smallest to largest and pencils are sorted from shortest to longest. One day, when practicing her counting skills, she noticed that some integers, have their digits sorted in non-decreasing order. She calls 8, 123, 555, and 224488 as numbers tidy. Numbers that do not have this property, like 20, 321, 495 and 999990, are not tidy.

She just finished counting all positive integers in ascending order from 1 to N. What was the last tidy number she counted?


The first line of the input gives the number of test cases, T. T lines follow. Each line describes a test case with a single integer N, the last number counted by Ananya.


For each test case, output is the last tidy number counted by Ananya.

1 ≤ T ≤ 100.

algrorithm super reduced string
Solution for super reduced string algorithm in php
User has n string in english lowercase. In one operation, he can delete any pair of adjacent letters with same value. User wants to reduce string as much as possible. To do this, he will repeat the above operation as many times as it can be performed. Help user to find and print most reducible form of string. If the final string is empty, print Empty String.
algorithm individual divisible digit
Solution for individual divisible digit algorithm in php

Given an integer, NN, traverse its digits (dd1,dd2,...,ddn) and determine how many digits evenly divide NN (i.e.: count the number of times NN divided by each digit ddi has a remainder of 00). Print the number of evenly divisible digits.



Note: Each digit is considered to be unique, so each occurrence of the same evenly divisible digit should be counted (i.e.: for N=111N=111, the answer is 33).
