Suppose we are at position (0, 0) We have a string represents consecutive directions using four letters. We have to check whether we can return at (0, 0) position after considering all of the given directions. The symbols areE for eastW for westN for northS for south.So, if the input ... Read More

Suppose we have a list of rectangles represented using its length and breadth. We can rotate any rectangle by 90 degrees so after rotating, the breadth will become length and vice-versa. We have to check whether we can sort the rectangles in non-increasing order of breadth.So, if the input is ... Read More

Suppose we have a binary string s whose length is 2 or more. We have to check whether we can rearrange s such that there are alternate 0s and 1s.So, if the input is like s = "1000111", then the output will be True as we can form "1010101" from ... Read More

Suppose we have three vectors x, y and z in 2D plane. We have to check whether we can get vector y from vector x by rotating it 90 degrees(clockwise) or adding z with it any number of times as required.So, if the input is like x = (-4, -2) ... Read More

Suppose we are at starting position p, we can jump at any direction (left or right) d1 and d2 units. We have to find minimum number of steps required to reach at position q by jumping from p.So, if the input is like p = 5, q = 10, d1 ... Read More

Suppose we have a coordinate point (x, y) and another value n. We have to check whether we can move from (0, 0) to (x, y) using n steps or not. We can move any of the four directions left, right, up and down.So, if the input is like p ... Read More

Suppose we have two matrices of size n x m named mat1 and mat2. We have to check where these two matrices are strictly increasing or not by swapping only two elements in different matrices only when they are at position (i, j) in both matrices.So, if the input is ... Read More

Suppose we have an array of n different second values. We have to check whether it is possible to start from 12'O clock and go back to 12 by only adding or subtracting the given seconds or not. We can use all given seconds exactly once, we can either add ... Read More

Suppose we have two strings s and t, and two values p and q. We have to check whether it is possible to get t from s such that s is separated into groups of p number of characters except the last group which will have characters ≤ p and ... Read More

Suppose we have three direction cosines l, m and n in 3-D space, we have to check whether it is possible to draw a straight line with these direction cosines or not.So, if the input is like l = 0.42426 m = 0.56568 n = 0.7071, then the output will ... Read More
