Implement an algorithm to sort a linked list.
Reverse a string.
Given a linked list which is sorted, how will you insert in sorted way.
Implement an algorithm to insert in a sorted list.
Delete an element from a doubly linked list.
Implement an algorithm to sort an array.
Given a sequence of characters, how will you convert the lower case characters to upper case characters?
Write a routine that prints out a 2-D array in spiral order.
Give a fast way to multiply a number by 7.
Write a function that takes in a string parameter and checks to see whether or not it is an integer, and if it is then return the integer value.
How would you print out the data in a binary tree, level by level, starting at the top?
Write a routine to draw a circle given a center coordiante (x,y) and a radius (r) without making use of any floating point computations.
Implement a TIC-TAC-TOE game assuming Computer as one of the player. Optimize it for fast computer play time and space. Do some analysis on memory and processing requirements .
You are given two strings S1 and S2. Delete from S2 all those characters which occur in S1 also and create a clean S2 with the relevant characters deleted.
Write a small lexical analyzer for expressions like "a*b" etc.
Given an array t which contains numbers between 1 and 99. Return the duplicated value. Try both O(n) and O(n-square).
Write efficient code for extracting unique elements from a sorted list of array.
Print an integer using only putchar. Try doing it without using extra storage.
Write a function that allocates memory for a two-dimensional array of given size(parameter x & y)
How would you do conditional compilation ?
Write an algorithm to draw a 3D pie chart ?
Write a funtion that finds repeating characters in a string.
Write a routine to reverse a series of numbers without using an array.
Write a function to find the nth item from the end of a linked list in a single pass.
Write a function to compute the factorial of a given integer.
Give me an algorithm for telling me the number I didn't give you in a given range of numbers. (Numbers are given at random).
Write a function that finds the last instance of a character in a string.
You have b boxes and n dollars. If I want any amount of money from 0 to n dollars, you must be able to hand me 0 to b boxes so that I get exactly what I request." The two questions were "What are the restrictions on b and n, and how is money distributed among the boxes?
What is the sum of the numbers from 1 to 1000?
You are an employer. You have ten employees. Each month, each one of your ten employees gives you ten bags of gold. Each bag of gold has ten pieces of gold in it. Each piece of gold weighs one pound. One of your employees is cheating you by only putting nine pieces of gold in each of his ten bags of gold.
You have a scale (not a balance, a scale), and you can only take one measurement from the scale, only one (1) reading.
How can you tell which of the ten employees is cheating you by using this scale and only taking one measurement?
How many points are there on the globe where by walking one mile south, one mile east and one mile north you reach the place where you started.
How would go about finding out where to look for a book in a library? (You do not know how the books are organized beforehand)
Imagine you are standing in front of a mirror, facing it. Raise your left hand. Raise your right hand. Look at your reflection. When you raise your left hand your reflection raises what appears to be his right hand. But when you tilt your head up, your reflection does too, and does not appear to tilt his/her head down. Why is it that the mirror appears to reverse left and right, but not up and down?
You have a bucket of jelly beans. Some are red, some are blue, and some green. With your eyes closed, pick out 2 of a like color. How many do you have to grab to be sure you have 2 of the same?
You are given a scale which you are to use to measure eight balls. Seven of these balls have the same weight: the eigth ball is heavier than the rest. What is the minimum number of weighs you could perform to find the heaviest of the eight balls?. Remmber it's a scale not a balance. (i.e. It can just tell you if one side is heavier than the other it can't give you the exact weight).
How would you design a toaster?
How would you design an universal remote control?
How would you design a clock for a blind person?
How many miles of road are there in the US?
There are n couples attending a party. Each one shakes hands with the persons he doesn't know. (Assuming each person knows his/her partner) Mary and John are a couple. John asked the rest of the party-attenders how many times he has shaken hands. Each one gives a unique answer. How many times does Mary shake hands?
