Jooney's Amusement Park

PKJ
 Coding Problem Keys   Jooney's Amusement Park   Problem Statement  In the amusement park at Jooney's amusement, there is a "Weighted Maze" challenge. This consist of a set of East West roads and North South roads (referred to as up down roads). There are N intersections and each intersection has a block of iron bar, the weight of which is given. You enter the maze at the top left corner. The exit from the maze is at the bottom right corner. Movement at any intersection is to the right or down provided a road exists in that direction. At each Intersection you pass through, you must exchange the weight in your cart with the weight of the bar at the intersection if it is heavier than the weight in you have in the cart. The objective is to determine a path through the maze along the roads so that one can exit the maze with minimum weight in the cart.  Input Format  The first line contains the number of intersections N.  Output Format  The f...

Function lengthOfLastWord - CTS Pattern

PKJ
 Coding Problem Keys   CTS Pattern   Function lengthOfLastWord   Problem Statement  You are required to fix all the logical errors in the given code. You can click on run anytime to check the compilation/execution status of the program. You can use printf to debug your code. The submitted code should be logically/syntactically correct and pass all test cases. Do not write the main() function as it is not required. Code Approach:  For this question, you will need to correct the given implementation. We do not expect you to modify the approach or incorporate any additional library methods. The function lengthOfLastWord (char *str, int len) accepts a string and length len as the input. The function return the count of last word in a given string. The function compiles successfully but fails to print the desired result due to logical errors. Your task is to debug the program to pass all the test cases.  Max Execution Time Limit: 5000 millise...
