from row 0 to row 1) while -1 indicates that we are moving up (e.g.
Positive 1 indicates that we are moving down (e.g. RowNumber tracks the current row to assign letters to, while direction tracks whether we are moving vertically down or diagonally up the zigzag. Next, we declare two variables called rowNumber and direction. For instance, if numRows equals 3, result =. The number of elements in result depends on the value of numRows. Within the function, we first declare and initialize a list called result using the statement Here, we declare a function called convert with two parameters – s and numRows. Solutionįor i in range(len(s)): #looping through each element Note that in the description above, we refer to the first, second and third rows as row 0, row 1 and row 2 respectively, to be in line with the zero-based indexing used in programming. For instance, if the number of rows is 3 and the string is PROGRAMMING, we can iterate through the string and assign ‘P’ to row 0, ‘R’ to row 1, ‘O’ to row 2, ‘G’ to row 1, ‘R’ to row 0, ‘A’ to row 1 etc. One easy way to do it is to iterate through the given string one character at a time and assign the character to the correct row. This program takes in two arguments – the original string and the number of rows. In other words, if given the word PROGRAMMING and asked to scramble it into 3 rows of zigzag letters, our program should return the string PRIRGAMNOMG. Our job is to write a program to scramble a given string using the zigzag layout described above. If we write the word in a zig zag fashion using 4 rows, we’ll get Layout, we can then concatenate each row to get the string
If we write this word in a zig zag fashion using 3 rows, we’ll get Join Rene Lynch on Google+ and Twitter.Today, we have another interesting challenge from Leetcode ( ) we’re going to scramble a given word following a zig zag fashion.įor instance, let’s consider the word PROGRAMMING. Scranton ignores judge’s ruling, cuts worker pay to minimum wageįormer Penn State president says he was unaware of Sandusky abuse Man’s 7th DUI involved collision, teen passengers - and a judge Moreover, there’s this: “An alligator typically bites and releases or bites and readjusts. Go for the eyes.” An alligator is typically looking for some easy eats, not a struggle. Fight for your life:“If you do find yourself in a situation where you have been attacked, don’t give up,” Mazzotti said. Everything you hear about running in a zigzag line is untrue.” If the alligator is attacking because you have trespassed into its territory, it just wants to run you off - not hunt you down, he said. True, alligators can move quickly on land - but only for short distances. “The shortest distance between two points is a straight line, and that’s the fastest,” Mazzotti said. And don’t believe that old tale about running in a zigzag fashion to throw off the gator. Run (in a straight line): If you find yourself face-to-face with a gator, get out of the way. And since they are moving around more, that brings them in more frequent contact with people.” With that, and the rainfall, that only makes them more active.
“The males and females have been spending lots of time with reproductive activities, so they are hungry. Or that recent rains tend to make alligators more active. Watch the weather, and the calendar: The teenager who jumped into the river might not have known that this is the tail end of alligators’ mating and egg-laying season. But a splashing human’s arm or leg can be mistaken for smaller, vulnerable prey in the water, such as a raccoon or possum. Alligators do not consider humans to be prey in part because of their size, he said. I know this sounds like common sense,” Mazzotti said, but it’s a tip that many people ignore. Avoid a gator’s territory: “If you see alligators in the water, don’t go in there. “When you do that, the alligator doesn’t know where the handout ends and the hand begins.” Don’t feed it:“That can cause trouble,” Mazzotti told the Los Angeles Times.
